Serena Williams recently crashed a friend's wedding wearing a leopard-pattern leotard-some of her Twitter and Instagram followers are saying she may have done it to get the attention of rumored boyfriend and coach Patrick Mouratoglou.

Several weeks ago, she posted on Twitter that she spent her night in bed with no invite to Sasha Bajin's house for a "pre Williams invitation event."

Is the Australian Open star Mouratoglou, lonely?

Serena Williams has been active on Twitter posting about her entrepreneurial and athletic successes, but she seems to be avoiding mentioning her boyfriend Patrick Mouratoglou.

The Australian Open star has, however, posted about her rival Maria Sharapova.

She mentioned earlier on that she liked Maria Sharapova's outfit on Twitter.

"I'm loving Maria S Nike outfit. #approved #supercute," the Australian Open star wrote.

Two weeks ago, she posted messages saying she spend the weekend at Zales and was watching the Bridezillas television show on Twitter.

"Another weekend... Spent at Zales this time I brought Venus," she wrote in one piece.

"Is it weird that I'm watching bridezilla all day???"
