Serena Williams’ second child is here!

The tennis star announced that she gave birth to baby No. 2 on TikTok Tuesday.

“Welcome my beautiful angel,” she captioned the video.

The Olympian shocked fans with her pregnancy in May by showing up to the Met Gala with her baby bump on display.

“Was so excited when Anna Wintour invited the 3 of us,” Williams captioned Instagram photos of her and husband Alexis Ohanian’s epic red carpet appearance.

Later that same month, the athlete, 41, shared a video of her 5-year-old daughter Olympia’s reaction to the news.

“Are you kidding me?” the toddler asked her parents. “Oh my God, I’m so excited.”

Williams and Ohanian welcomed Olympia in September 2017 — and the new mom barely survived the emergency C-section.

She “fought hard” to get nurses to listen to her fears and do a CAT scan, where a blood clot was discovered in Williams’ lungs.

“They needed to insert a filter into my veins to break up the clot before it reached my heart,” she recalled in an April 2022 Elle essay.

“Being heard and appropriately treated was the difference between life or death for me.”

Watching Williams experience the “near-fatal complications” was “traumatizing” for her husband, Ohanian, 40, told The Guardian in January 2020.

Two years later, however, the couple decided to give Olympia a younger sibling.

“Whenever we’re ready, we can add to our family,” Williams explained in her Vogue cover story in April 2022 while revealing her tennis retirement.

“I definitely don’t want to be pregnant again as an athlete,” she continued at the time. “I need to be two feet into tennis or two feet out.”.

Williams and Ohanian have been married since November 2017.
