Serena Williams emerged victorious in the China Open on Sunday, leaving many wondering if her net worth has increased.

The American tennis star defeated Jelena Jankovic of Serbia, winning her tenth title of the year.

But Serena Williams has also made headlines for her relationship with coach and rumored boyfriend Patrick Mouratoglou.

Patrick Mouratoglou is usually in the stands to watch her matches but does not come down to the court for coaching in-between sets, TennisWorldUSA.org also reports.

Serena Williams has captured the attention of fans throughout her performance at the China Open, but many fans are also wondering if she's still dating her coach and rumored boyfriend Patrick Mouratoglou - she hasn't shown any public display of affection since the US Open.

While her coach has supported her on his Twitter page with messages that point to her success within the tournament, Serena Williams hasn't stopped to show any affection for Patrick Mouratoglou.

Shortly after the U.S. Open, Serena Williams denied rumors surrounding her relationship with her coach saying "You just do not mix pleasure with business, I firmly believe in not mixing pleasure with business."

A hockey player named Dan Ogee posted a photo of a trophy he appears to have won and tagged the US Open star in his post, saying "my trophy is bigger than yours."

Serena Williams responded, saying "Wow can I have it?" and he answered back, saying "Nope, but you can drink from it."

Perhaps the Twitter back-and-fourth exchange might have made Serena Williams' coach and rumored boyfriend Patrick Mouratoglou jealous?

Serena Williams has spoken about all about her personal and social life on Twitter, except for her coach and rumored boyfriend Patrick Mouratoglou.
