Serena Williams may have accidentally hinted that her pal Meghan Markle will soon welcome a baby girl — and everyone took notice.

In an interview with E! News, the tennis superstar was asked whether she thought Meghan would make a good mother. Williams replied, “She’ll be the best mom, for sure.”

And that’s not all. When asked about advice she had for fellow parents, the tennis star told E! News, “Accept mistakes and don’t expect to be perfect. We put so much pressure on ourselves.”

She then added, “My friend is pregnant, and she was like, ‘My kid’s gonna do this,’ [and] I just looked at her like, ‘No, she’s not. No, you’re not. She was like, ‘I need to talk to you about tips,’ because, yes, I had all of those high expectations.”

Williams referenced her friend’s baby as “she” and, obviously, royal fans are freaking out. Could this mean that Meghan is actually having a baby girl? We shall wait and see.
