Serena Williams recently tweeted about enjoying her mother's comfort food, leaving many fans wondering if her coach and rumored boyfriend Patrick Mouratoglou is allowing her a cheat day on her athletic diet after a successful performance at the Australian Open.

"Mama made fried chicken, Mac and cheese, yams, broccoli, and lots more. #comfortfood yummy. I love mommy," she wrote on Twitter.

Last week, Patrick Mouratoglou posted a Facebook photo of the American tennis star in  a pink Nike tennis ensemble.

"Just before Serena's match during the warmup," Patrick Mouratoglou captioned the photo.

"Wow, isn't this lady Fashionista....?" a fan responded to the photo.

Earlier this week, the French tennis legend was featured in a 26minute documentary about his tennis academy.

"Watch the new 26 minutes documentary on MOURATOGLOU TENNIS ACADEMY about the Mauritius preparation wednesday at 2.45pm (1.45 pm in the uk), on Eurosport France and International (54 countries)," he posted on his Facebook account.

Serena Williams retweeted Miley Cyrus' post about listening to Brittney Spears' "Sometimes" love song, leaving many wondering if it could be related to her relationship with coach and rumored boyfriend Patrick Mouratoglou.

"One of my fav songs. When needed I repeat this too," Serena Williams wrote on Twitter.

"I wanna believe in everything that you say 'cause it sounds so good," one line of the song reads.

"But if you really want me move slow. There's things about me you just have to know."
