Serena Williams confirms baby's gender will be a 'surprise', admits she even tricked sister Venus

Not so fast!

Serena Williams is setting the record straight about the sex of her unborn baby after her sister, Venus, appeared to confirm that she is expecting a little girl.

During a post-match interview at the French Open on Wednesday, Venus used the pronoun "she" when asked if Serena had picked out any baby names.

"She's going to call me the favourite aunt," she told Eurosport. "Of course we're all like baby V, baby Lyn, baby Esher, we all want the baby to be named after us."

But it seems that it was all a clever ruse created by Serena to keep the baby's gender under wraps, even from her own family!

In an Instagram post on June 1, she shed some light on her sister's comments.

"I think the surprise of knowing what you are going to have on that very special day you give birth is prob the best surprise you can ever have!" she wrote, along with a heart-eyed emoji.
