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.
