Serena Williams Boyfriend 2013: Should Patrick Mouratoglou Be Jealous Of Sascha Bajin? Tennis Star Tweets About Loving Date Night

Serena Williams posted a message on Twitter on Sunday mentioning that she loves "date night with @BigSascha and @Estaleemob," leaving many fans wondering if her coach and rumored boyfriend Patrick Mouratoglou should be jealous.

Sasha Bajin, who describes himself as Serena's "hitter, bodyguard, chef, boyfriend and ex husband" on his own Twitter page, mentioned that he loves "going out with 3 beautiful ladies."

Serena Williams may have had a negative reaction to a CNN article mentioning that her coach and rumored boyfriend Patrick Mouratoglou "rescued" her from her declining tennis career.

"Mouratoglou gives all praise to Serena, minimizing his impact by saying his role is to 'reduce [her] chances to lose to the strict minimum.' Murphy follows a well-trodden path of Mouratoglou-as-catalyst that countless outlets, including The New York Times, The Times of London and USA TODAY Sports, have already covered. There's no denying Mouratoglou has been a boon to Serena's tennis," USA Today writes.

"Either way, Serena's game and confidence needed some fine-tuning, which Mouratoglou provided. She doesn't appear to need anything else."

Shortly after CNN's piece was published, Serena Williams wrote this on Twitter: "Philippians 4:13 'For all things I have the strength by virtue of him who imparts power to me.' Never. From. Man."

Serena Williams needs to keep winning major tournaments to stay on top of her game, Bleacher Report posits, leaving fans wondering just how her coach and rumored boyfriend Patrick Mouratoglou will do so.

"She has won two majors each for the past two years, and it's important that she keeps up that pace if she wants to challenge Graf's 22," the website writes.
