Whoopsie!

Venus Williams seemed to let it slip that pregnant sister Serena is expecting a baby girl during an interview with Eurosport on Wednesday, and we have to hand it to the interviewer for the way he chose to phrase the question. "What is the baby going to call you?" he asked, and that's when he got the big reveal!

"She's going to call me β€˜favorite aunt.' We're all like, 'Baby V, baby Lyn, baby Isha.' We all want the baby to be named after us," she blurted out. That pretty much confirms it - break out the pink!

In other baby news, Lauren Conrad just took to Instagram to show off her bare baby bump in a bikini and launch her new swimwear line. No word on her baby's gender, but maybe Venus could give us a hint about that too!
