Olympia sings karaoke with mom Serena

Just a few days after her first tennis lessons, Alexis Olympia Ohanian Jr. is picking up another of her mom Serena's favorite pastimes: karaoke.

Three-year-old Olympia and her mom sang to the tune of "Paw Patrol", a popular cartoon on Nickelodeon. Serena is a huge fan of karaoke, singing up a storm regularly all around the world.

She's done it all from pop:

And disco:

To rap:

And now Nickelodeon.

But what's Serena's go-to song for when she's on stage?

"It depends, you have to know your crowd," she told Michael Strahan and Sara Haines on Good Morning America last year. “Like I was going karaoke the other day in California, but way down south, so I was like OK I'm going to sing Selena. It's really about knowing the crowd."
