Serena Williams Twitter: Boyfriend Loneliness? Australian Open Star Spends Night In Bed Alone

Serena Williams 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, who is rumored to be dating coach and rumored boyfriend Patrick 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???"

She also posted several Twitter photos of herself having fun at the Vanity Fair Oscars Party 2014.

Serena Williams also made a Twitter status mentioning that she is "alone" and "unaccompanied" just after rumored surfaced of her hooking up with Drake.

The Australian Open star was confronted by Rihanna, who is also rumored to be hooking up with the singer, at his Paris concert, HollywoodLife.com reports.

The tennis star approached Rihanna backstage and had it out with her but nothing physical happened, and Rihanna's security team was standing by in case anything truly nasty went down, HollywoodLife.com also reports.

She also posted the message "everybody needs love" on Twitter.

Shortly after posting the message, several of her fans reassured her that they love her.
