Serena Williams posted ominous messages that appear to talk about her personal life on Twitter, leaving many wondering if she has dumped her coach Patrick Mouratoglou as a boyfriend.

"No it's not forever. It means until they or you are finished," the American tennis star wrote in a post.

"When it comes to relationships - forever could have a different meanings for sure - long list," responded one Twitter fan on her page.

Serena Williams might have given her coach and rumored boyfriend Patrick Mouratoglou a scare, but quickly avoided it - a fan on Twitter asked her if she would twerk if she wins the Australian Open and she quickly responded saying "Lol no way"

Other fans responded to the post also responded "Lmfao.. good answer!"

But Serena Williams appeared to be in pain during her last three matches at the China Open and had to take a medical timeout after complaining about back pains, leaving many fans wondering if her coach and rumored boyfriend Patrick Mouratoglou is wearing her out with all of the tournaments he is making her participate in.

"I've been a little tight all week. It's been a long year, so I was really happy," Serena Williams mentioned during a public interview following the final of the China Open.

Serena Williams has never used the on-court coaching rule which has been implemented on the tennis court for the last couple of years, TennisWorldUSA.org reports.

Her coach and rumored boyfriend 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.
