The couple first revealed their baby news on TikTok Tuesday, where Williams shared a video that begins with the family sitting at a table, with daughter Olympia, 6 next month, leaning on Williams as Ohanian types on a laptop in front of them.

Williams then gets up and says she'll be right back and returns with a tightly swaddled newborn. The video ends with Polaroid-style shots of the new family of four.

"Welcome my beautiful angel," she captioned the TikTok.

Speaking with PEOPLE in June, Ohanian was looking forward to getting the hang of having a newborn in the house again.

"I think I've I've definitely forgotten what it's like to have a new one around, so it might be a rude awakening, maybe literally," he said with a laugh. "But right now, we're excited."

Ohanian also talked about feeling more confident the second time around, noting, "We're not first-time parents anymore. I feel more confident about having a newborn, all of those things that I just had zero confidence about with Olympia because I’d never even been around babies at that point in my life."
