Serena Williams’ second baby is on the way!

The athlete announced that her and husband Alexis Ohanian’s family is expanding while walking the Met Gala 2023 red carpet Monday.

The pregnant tennis pro’s budding belly — and new bob hairstyle — were on display in a black Gucci gown as she posed for pics.

“I’m feeling good,” the tennis pro, 41, gushed. “I can breathe. I can stop not hiding.”

Minutes ahead of her reveal, Williams shared the news with her Instagram followers.

“Was so excited when Anna Wintour invited the 3 of us to the Met Gala,” she captioned sweet snaps cradling her stomach.

Williams and Ohanian, 40, have been married since November 2017 and are the parents of 5-year-old daughter Olympia.

The little one was born in September 2017.

Two years later, the Olympian told Page Six that she wanted to give her child a sibling as close to her age as her own older sister, Venus Williams.

“It’s getting farther and farther away,” Serena said in the December 2019 interview. “I’m like, ‘That ship has sailed.’ We’ll see, I obviously want more.”
