A large black and white picture of Serena Williams is on display at Patrick Mouratoglou's tennis academy, where his ex-wife Clarisse Mouratoglou used to work, according to the Daily Mail.

Clarisse Mouratoglou, who works as an interior designer in France, still works with her husband at his company, PM Management Consulting, the Daily Mail also reports.

But now that the two are splitting, Clarisse Mouratoglou is slowly beginning to distance herself from her ex-husband's businesses - Patrick Mouratoglou runs five companies centered on tennis and management.

It is rumored that Serena Williams' romantic relationship with her coach was the reason for Patrick Mouratoglou's split from his ex-wife, with whom he shares two daughters.

But neither has commented on the love affair or the divorce.

Serena Williams currently owns an apartment in Paris, where she joined Patrick Mouratoglou's tennis academy a year ago, and stays there on a frequent basis - the couple has been spotted shopping and spending romantic walks together throughout the city.

Rumors surrounding the couple sparked after photographers witness Serena Williams with her hand inside Patrick Mouratoglou's back pants pocket  on a Paris street. Since then, multiple reports have speculated that the two are a couple and that they are keeping their relationship clandestine.

Serena Williams also caught the attention of several media after her dispute with Russian tennis star Maria Sharapova, who criticized the American tennis star's relationship with Patrick Mouratoglou because of their secrecy and past relationships.
