Cutest doubles duo? Serena, baby Olympia take the court

Just when you thought Serena Williams and her daughter Alexis Olympia couldn't get any cuter, they find a way. The mother-daughter duo recently took the court, and the world was not ready for it.

The 23-time Grand Slam champion and 2-year-old wore matching purple catsuits and shared the same side of the net.

"Her squat in the 2nd pic I'm crying," Eugenie Bouchard wrote in response to Serena's latest photo.

Who isn't crying? That's the question we have to ask. The doubles duo didn't just capture attention from the top pros; Gigi Hadid and actress/singer Zendaya also commented on the Instagram post.

However, the Australian Open Twitter account may have won the best comment award.

Serena claimed her last Grand Slam title at the Australian Open back in 2017, but she didn't do it alone. She was in the early stages of pregnancy when she defeated sister Venus Williams in the final.

Alexis Olympia may only be 2, but she's already been a part of winning a major trophy. It sure does say a lot about what tennis fans can expect from her in the future.

For now, fans can certainly expect more overwhelmingly cute photos and videos from the two stars.

"I just love her and you too much!" Venus said. "If this gets any cuter I will NOT LIVE."

With over 31,000 comments on Serena and Olympia's photo series and over 100,000 likes on the Australian Open's repost, Venus may be speaking for the entire world.
