Meet Alexis Olympia Ohanian, Jr.: Perhaps the only fetus to win a Grand Slam Title with Serena Williams eight-weeks pregnant.

Serena Williams became a mother on Sept. 1, giving birth to a baby girl at St. Mary’s Medical Center in Palm Beach, Florida. Alexis wasn’t discharged from the hospital until Sept. 7 because of complications, according to a video Williams shared on Wednesday.

The video, which is compiled of her and fiancé, Alexis Ohanian’s Snapchats.

It turns out, Williams knew she was pregnant even when she won the Australian Open women’s single final back in January.

The 33-year-old tennis star captioned a Snapchat: “No one knows I’m 8 weeks pregnant,” while she was holding her Open trophy with cameras constantly snapping shots in the background.

And that’s true. No one had any clue Williams was pregnant until she accidentally posted a Snapchat in a yellow one-piece swimsuit with the caption: “20 weeks.” The Snapstory was quickly deleted, but a screenshot of the picture made it rounds on Twitter and a spokesperson later confirmed William’s baby would be born in the fall.

Williams, 35, got engaged in December to Ohanian, the co-founder of Reddit.
