Serena Williams and Caroline Wozniacki: Tennis' perfect match

It can be tough and lonely at the top, but Serena Williams has got a pretty cool sidekick to keep her company.

Although there are nine years and 21 grand slam titles between them, the American tennis star's friendship with Caroline Wozniacki is the real deal.

Their head-to-head record might be a little one-sided -- Williams has a 10-1 record against the Dane -- but off the court they are genuinely close.

"Caroline is really honest, she's really real," Williams told CNN's Open Court.

"She's one of my true friends that will tell me the truth no matter what because she doesn't have anything to gain or to lose, and that's what I love about her."

Friendships between individual athletes at the very top of professional sport can be rare -- especially when millions of dollars of prize money is at stake.

But Williams is taking a completely different tack to other former champions.

Steffi Graf, the 22-time grand slam winner, was a rather private person, while Maria Sharapova is known to keep herself to herself while on tour.

Yet Williams is grateful to have Wozniacki alongside her as she negotiates life on tour, where players spend days and months away from friends and family.

"She's really sweet, she's really, really loving -- but most of all she is kind and she is giving," Williams added.

"I'm a little older than Caroline, but mentally she's older than me so it really works out great."

The friendship between the two women has been well documented -- notably on Instagram.

The dominant force in women's tennis, the 34-year-old Williams enjoyed one of the most impressive seasons of her illustrious career in 2015.

She won three of the four grand slams and is the oldest woman to have held the world No.1 ranking.

Wozniacki, whose only win against Williams came in Miami three years ago, has yet to sample the taste of grand slam success.

Now ranked 17, the former world No.1 is rebuilding her career after reaching the summit at the age of just 20.

The past year has been difficult for Wozniacki, with her form affected by a spate of injuries.

It was particularly disappointing given her success in reaching the 2014 U.S. Open final -- her first at a grand slam since 2009 -- where she was beaten in straight sets by Williams.

But the two have grown closer since, particularly after Wozniacki's breakup with golf star Rory McIlroy in May that year -- which came after the wedding invitations had been sent out.

"She's always been there for me -- even when I was going through tough times," Wozniacki told CNN.

"She was the first one there but she's also been there for some of the greatest and most fun times."

Williams was one of the first people on the phone after the news broke, and they have cemented their friendship since -- whether it be on the dance floor or at a basketball game.

It turns out Williams' prodigious tennis ability isn't her only talent.

"She sings great karaoke," says Wozniacki. "She's a great cook. She says she doesn't like sweets, but she also steals my sweets when I have them lying around."

Serena Williams: Knee injury forces world No. 1 to pull out of Hopman Cup

World No.1 Serena Williams has withdrawn from the Hopman Cup as she continues to manage a knee injury ahead of her Australian Open title defense.

The Hopman Cup's Twitter feed confirmed Williams had pulled out of the tournament, after the American had to cut short her first match of 2016 because of an inflamed left knee, leaving the court a set and 2-1 down against Australia's Jarmila Wolfe.

Earlier in the week the injury had also ensured Williams had been unable to play her opening match at the traditional team warmup tournament ahead of the new season's first grand slam.

Serena Williams: World No. 1 hit by injury

"I just have some inflammation that's been going away very slowly. It is going away but it needs a little more time," Williams told reporters at the Perth event.

"Usually I'm super-fast and I wasn't moving the way I like to move. Mainly I was afraid to move.

"I've been training really hard in the off season and pushing myself beyond the limits so a little rest, a little treatment, a day or two off will make a world of difference.

"It's not even a bump -- just a really minor thing in the road and I'll fly over it."

The 34-year-old is coming off a brilliant 2015 season in which she won the Australian Open, French Open and Wimbledon -- taking her tally to 21 grand slam singles titles -- before a surprise defeat in the U.S. Open semifinals.

"The whole year was great," Williams reflected. "But it was also physically very, very difficult. I'm looking forward to this year and making the best of it."

Asked whether she had decided whether to play at the Australian Open, which begins in Melbourne on January 18, Williams added: "I'm just taking it a day at a time still. I'm not making any decisions now."

Williams' injury has added to concerns over the fitness of a cluster of stars in the women's side of the draw at the Australian Open.

Last year's runner-up Maria Sharapova withdrew from the Brisbane International, where she was the defending champion, because of an arm injury.

"I hurt my forearm in practice a couple of days ago and need to withdraw as a precaution," the fourth-ranked Russian told reporters.

Soon after, world No. 2 Simona Halep also scratched her name from the contenders' list in Brisbane, citing a left leg problem.

In the men's half of the Brisbane draw, world No. 3 Roger Federer opens his title defense Thursday against German qualifier Tobias Kamke.

"People like to talk about this tournament as a preparation for bigger things, but I don't really see it that way," Federer told reporters. "Every tournament I play is important to me. This is a tournament I want to win."

Federer is the top seed in the men's draw, with world No. 2 Andy Murray on duty for Great Britain in the Hopman Cup and No. 1 Novak Djokovic competing in the Qatar Open in Doha alongside 2009 Australian Open winner Rafael Nadal.

Serena Williams: Watch 'superhero' tennis star stop phone thief

Watch as "superhero" Serena Williams stops a thief who tries to steal the tennis superstar's phone from a restaurant.

Williams, who later described the incident in full on her Facebook page, said that she received a standing ovation when she returned to the restaurant with her phone.

The 21-time Grand Slam champion wrote: "I just showed every man in there I can stand up to bullies and other men. It was a win for the ladies!"

Serena Williams plays Superwoman to get her cell phone back

Say you’re out for Chinese food in San Francisco when a stranger walks over, grabs your cell phone and makes a run for it. What do you do?

If you’re tennis star Serena Williams, you don’t wait for the man you’re dining with to play knight in shining armor. You leap up, chase the thief through the restaurant and down the sidewalk, confront him — politely — and get your phone back.

“Omg that dude took my phone!!” Williams, 34, posted on Facebook about her Tuesday night encounter with a thief at Mission Chinese. Alongside a photo of herself dressed as Superwoman, Williams recounted the tale in prose as breakneck as a volley at Wimbledon.

“Not thinking I reacted (hence the superwoman photo) I jumped up, weaved my way in and out of the cozy restaurant (leaping over a chair or two) and chased him down. He began to run but I was too fast. (Those sprints came in handy) I was upon him in a flash!”

The restaurant’s surveillance video showed a bald man in a white shirt carrying a jacket and walking by the four-person table where Williams and a bearded companion were seated across from one another. Williams’ phone and other items were on a chair to her left. The man passed the table, turned, retraced his steps and fiddled with his jacket.

The video shows Williams looking down at the chair beside her and appearing to notice something wrong and standing up. The video cuts to the man leaving the restaurant. Williams is seen seconds behind him. Outdoor video showed her striding up the Mission Street sidewalk and approaching the man, who put on his jacket as he turned to face her.

Williams continued the narrative on Facebook:

“In the most menacing yet calm no nonsense voice I could muster I kindly asked him if he ‘accidentally’ took the wrong phone. He stumbled on his words probably not expecting this to happen. While he was thinking of the right thing to say and eventually he said ‘Gosh you know what I did! It was so confusing in there. I must have grabbed the wrong phone.’”

Lindsey Vonn ‘Really Proud’ Of Serena Williams Despite ‘Brutal’ US Open Loss

The weight of a nation proved too hard for Serena as she crashed out of the US Open during the semi-final stage, but Olympic gold medalist Lindsey Vonn has nothing but respect for the tennis great, HollywoodLife.com can EXCLUSIVELY reveal.

We were all left a little deflated when Serena Williams, 33, lost to Roberta Vinci, 32, in the US Open semi-finals on Sept. 11. Despite her shocking loss, fellow sports great Lindsey Vonn, 30, has revealed she’s very proud of the tennis legend, HollywoodLife.com has EXCLUSIVELY learned! Find out what she had to say.

We caught up with Lindsey at the Rebecca Minkoff Spring 2016 show during NYFW on Sept. 12, and asked her how she felt about Serena’s defeat to Roberta, who ended the world number one’s quest for a Grand Slam. “I was really disappointed,” Lindsey told HollywoodLife.com EXCLUSIVELY. “I understand Serena’s position, it’s just really brutal and sometimes you have off days, and unfortunately it was at a really bad time, but she played such an amazing tournament and technically she’s won 4 grand slams in a calendar year. I think she’s an amazing athlete and I’m really proud of all she’s accomplished.”

That’s nice of Lindsey to say, who has also suffered her own disappointments in her professional sporting career. Lindsey missed the 2014 Sochi Olympics after suffering a knee injury, and was unable to defend the downhill gold she had won at the 2010 Vancouver Olympics so famously. But maybe, just maybe, she will be fit enough and ready for the 2018 Winter Olympics in ‎Pyeongchang, South Korea. Fingers crossed!

Twitter blames Drake for jinxing Serena Williams

Serena Williams lost the most heart-breaking match of her career during the U.S. Open yesterday, and the Internet has blamed her rumored new boyfriend, rapper Drake, for the loss.

Williams lost in her semifinal match to Roberta Vinci of Italy on Friday afternoon 2-6, 6-4, 6-4.

Soon after her bid for the first Grand Slam since 1988 came to a halt in shocking fashion, the hashtags 'blamedrake' and 'drakecurse' started trending on Twitter.

'Wherever Drake cheers, losing follows. The curse continues. #SerenaWilliams', one social media user shared on Friday.

'Drake jinxed Serena man,' another person wrote on Twitter.

The popular theory blaming the rapper for her loss circulated on social media with several users taking hits at him.

"Drake is the Jessica Simpson to Serena's Tony Romo" one user wrote on Twitter followed with the hashtag 'BlameDrake'.

"Drake jinxed Serena man," another user posted on the social media site.

The hip-hop mogul, who stood in the stands rooting Williams on, had even before Friday developed a reputation as bad luck for teams and athletes.

For example, Drake watched on as his favorite college team the Kentucky Wildcats, whose undefeated season ended in the semifinals of the NCAA Tournament against Wisconsin Badgers.

He has also been blamed for Cleveland Browns quarterback Johnny Manziel's 'lackluster' career, the Seattle Hawk's most recent Super Bowl loss and for LeBron James's cramps during his last year playing with the Heat, according to the Washington Post.

This is not his first time he has attended one her matches as he has been pictured previously during the Rogers Cup in 2011, but Williams won 4-6, 6-3, 6-3 against Zheng Jie.

After the match a heartbroken Serena was spotted leaving the stadium with her rumored boyfriend Drake, with the two getting into the same car and driven away from the facility.

Serena did not even change before leaving, seeming to want to get out as quickly as possible following her loss.

Vinci, who is unseeded, will now take on countrywoman Flavia Pennetta in the final on Saturday.

Pennetta upset Simona Halep - the number two seed - earlier in the day.

Serena seemed to be well on her way to the final after blasting past Vinci in the first set, but the Italian began rallying better in the second set, and by the final games of the third Serena appeared exhausted on the court.

By the time Vinci hit her final winner - a volley at the net - Serena appeared ready to leave.

She graciously shook her opponent's hand before immediately leaving the stadium, waving to the fans as she made her exit.

Serena appeared to be having problems with her ankle during the match and had the trainer tend to her at one point.

Serena, 33, had not lost in a major since Wimbledon in 2014 prior to her defeat on Friday, and had only lost two matches this season.

Serena kept things brief during her press conference following the match, saying; 'I don't want to talk about how disappointing this is for me. If you have any other questions I'm open to that.'

She did compliment Vinci's performance during the match.

I thought she played the best tennis in her career,' Williams said.

"You know, she's 33, and you know, she's going for it at a late age. So that's good for her to keep going for it and playing so well.

"Actually, I guess it's inspiring. But, yeah, I think she played literally out of her mind."

When asked about the pressure put on her by those hoping to see her win the Grand Slam, Serena said; 'I told you guys I don't feel pressure. I never felt pressure. I don't know. I never felt that pressure to win here. I said that from the beginning.'

The entire press conference lasted exactly three minutes.

Rumored boyfriend Drake cheered Serena on during the match from a private suite, and some are now jokingly blaming her loss on him.

Serena was aiming to become the first woman since Steffi Graff in 1988 to win all four majors in the same calendar year.

She was also aiming to match Graff's record of 22 Grand Slam singles titles, the most of any player in the Open Era.

Prior to Friday, she had never lost to Vinci, who at 32-years-old is just a year younger than Serena.

What's more, she had never even lost a set to Vinci, and defeated her in Toronto last month.

Vinci apologized to the crowd after her victory.,

"For the American people, for Serena, for the Grand Slam and everything,' she said.

"But today is my day. Sorry, guys.'"

She then added; 'It's an incredible moment for me. It's amazing. It's like a dream, you know? I'm in the final. I beat Serena. I think [it's] the best moment of my life.'

When asked later about how she managed to play so well, Vinci told reporters; 'In my mind, I say put the ball on the court. Don't think.

'Try to put all the ball on the court. Don't think about that Serena is in the other court. And run, you know, when you put the ball, run. Don't think and run. And then I won.'

Vinci used her trademark slice expertly in the final two sets, making it near impossible for Serena to generate any pace on the ball and forcing her to play Vinci's game.

She grew increasingly frustrated during the contest, receiving a code violation at one point for smashing her racket.

Vinci now becomes the lowest ranked played to reach the finals of the US Open since 1997 - when Serena's sister Venus took on Martina Hingis.

Serena played her sister in the quarterfinals here in another three set match, pulling out that victory 6 - 3 in the third.

Vinci and Pennetta - who used to be roommates - played each other in the quarterfinals of the 2013 US Open, with Pennetta winning in two sets.

Speaking with ESPN, Serena's mother Oracene Price - who seldom comments on her daughters - admitted that she appeared to be felling the pressure of the Grand Slam bid.

Her coach Patrick Mouratoglou added that she did not appear to be herself when he spoke to her earlier in the day.

Despite a high number of unforced errors - 40 to Vinci's 20 - Serena had a good day, hitting 50 winners and winning 93 points, more than her opponent who had 80 for the match.

She did suffer four breaks of serve, but also managed to break Vinci four times as well.

Serena also had four double faults, which were balanced out by her 16 aces.

Serena Williams Contemplates Life After Tennis

Williams will not actually launch her North American hard court campaign until Tuesday or Wednesday against Italy’s Flavia Pennetta, so all of Monday’s action took place in a posh VIP lounge where the world number one took questions from the media.

The 33-year-old Williams, with her 21 Grand Slam titles and more than 15 years of elite play, is an intimidating presence to most opponents.

Well rested and relaxed after sitting out the Stanford event with a sore right elbow, Williams was asked by a playful Wozniacki, “obviously I am the coolest person you know, why is that?”

But the tennis pro insists that it’s not necessarily her language or temper that are the real problems, but sexism – as men who’ve had similar outbursts receive considerably less attention and criticism for them.

Recently Serena Williams showed off her love possibly for her boyfriend Patrick Mouratoglou on Instagram. I’ll just do athleticwear’.

Besides looking tres chic for photographer Norman Jean Roy, Williams talks about racism, her budding fashion career and that Grand Slam thing in an interview with writer Kerry Howley.

“It was special for both of us”, the 25-year-old from Denmark said. “It was great when Chris Evert was around”. But the “90s was not a good time”.

The profile itself largely focuses on Serena’s unparalleled dominance in tennis and her post-retirement fashion ambitions-the story starts with her ineffectively trying to sell her line, Serena’s Signature Statement Collection, on HSN. And if she looks like a natural at modeling, that’s because she had plenty of practice last year when she graced the cover of Vogue (for the second time). “I’m really happy with my body type, and I’m really proud of it”.
