Venus Williams may have accidentally revealed the gender of sister Serena Williams’ baby during a post-match interview at the French Open this week.

When asked by Eurosport what the baby will call her, the 36-year-old professional tennis plater replied, “she’s going to call me favorite aunt.” Venus added that she and her other sisters are pushing for the child to be named after them.
