Tennis superstar Serena Williams and Duchess Meghan Markle are very good friends, and Serena helped throw her baby shower earlier this year.

The two have been relying on each other. 

When speaking about advice she had for fellow parents, Serena said, “Accept mistakes and don’t expect to be perfect. We put so much pressure on ourselves.”

Serena continued:

“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.”

Serena didn’t name Meghan directly, but everyone is noting that she also used “she” to describe the child.

Serena just possibly blew it. 

Royal groupies will not be happy.
