Serena Williams: Beyonce, Rafael Nadal, more stars react to baby news

Jennifer Kline,

Serena Williams gave birth on Friday -- and just minutes after the news broke, one star had already taken to social media to recognize the tennis icon.

"Congratulations Serena!" read a photo posted by Beyonce on Friday afternoon.

After Bey, the well-wishes started pouring in from all over Hollywood. "You Reddit here first!" joked Wendy Williams, referring to Williams' fiance, Reddit co-founder Alexis Ohanian. "Congratulations!"

One important person who couldn't take to social media right away? Sister Venus Williams, who was just about to walk onto the court for a US Open match when she offiically became an aunt. In true Williams fashion, she kept her head in the game -- although she told ESPN, "Obviously I'm super excited. Words can't describe."

This is the first child for both Williams and Ohanian, who got engaged in December 2016.
