Serena Williams flaunted her fit bikini body this week while on vacation with her rumored boyfriend, French coach Patrick Mouratoglou.

While on a boating trip in the Republic of Mauritius, Williams is seen getting close to Mouratoglou.

In September, Williams was spotted in Paris with Mouratoglou, sparking speculation that the two were an item.

 

"If it was anybody other than Serena on the other side of the court, I'm not sure we'd be talking now," Mouratoglou, who has been working with Williams recently, told the Associated Press, after the tennis champ's U.S. Open win this summer. "But it was Serena. She was there. She's a winner and she's a champion."

 

Days later, the two were snapped in the city of love, with their hands in each other's pockets, and embracing as they walked down the streets.

This is not the first time Williams and Mouratoglou have been seen together in Paris. In June, they also sat next to each other at the French Open.

After winning the U.S. Open, Williams talked to the AP about dating following news another tennis player, Maria Sharapova, announced the end of her engagement to basketball player Sasha Vujacic.

"If I'm in a relationship, I'm fine; I do well. But I feel like when I'm out, I'm angry and I do even better," Williams said, with a laugh. "I don't know what's better for me. It's a win-win situation."

During the early rounds of the U.S. Open, it was speculated that Williams had reunited with ex-boyfriend Common, who cheered her on during the third-round women's doubles match. As Common, 40, entered the stadium, he went straight to Williams' mother, Oracene Price, and her friends and family, and sat with them to watch the match.

Now, it seems from the photos of Williams with Mouratoglou that she might have another love interest in mind.
