"But the lady had no idea that it's my daughter, so we'll see how that goes."
In a video posted to Instagram, Williams revealed her 3-year-old daughter Olympia is starting tennis lessons.
"I'm not a pushy mom, but I know how I like technique. So I'll make sure she's good at teaching Olympia some techniques."
In the video she showed off Olympia's very own tennis racket: "Look, Olympia got a cute racket like mine."
She also shared a video of her and her daughter watching old tennis matches to study before her first lessons.
However, Olympia had other viewing plans, and the pair ended up watching a cartoon instead.
Williams gave an update from the lesson while also wearing a mask.
"So she's at her tennis lesson, but I'm gonna leave so I'm not distracting."
"I know how to leave and be. I'm not, like, an overprotective mom ... no matter what Alexis [Ohanian, her husband] says."
