Did Venus Williams accidentally reveal Serena is expecting a baby girl?

Venus Williams may have accidentally announced that her pregnant sister, Serena, is expecting a baby girl Wednesday at the French Open.

After dispatching Japan's Kurumi Nara in straight sets during the second round at Roland Garros, Venus was asked what she wanted her little sister's baby to call her, the Associated Press reports.

"She's going to call me, `favorite aunt'," Venus responded.

Serena, who is about six months pregnant, was in the stands on Wednesday to root on her older sister.
