Alec Baldwin and his wife, Hilaria Baldwin, will be welcoming their fourth child in the spring!

On her Instagram account, the fitness guru shared a photo of herself with her husband and three children and announced that she’s expecting. Hilaria also told her 267,000 followers on social media that she will be announcing the gender of her baby on Saturday.

In a follow up post, Hilaria shared a snap of the cute cake she made as part of her gender reveal this weekend. The cake is filled with funfetti and a combination of the colors pink and blue. The wellness expert said that her three kids will be the one to cut the cake so they are first to know if their fourth sibling is a boy or girl.

Last month, she spoke with Access Hollywood and said that she’s open to having more kids. At that time, Hilaria was already pregnant, but did not confirm it yet. “For some reason, right after I deliver a baby I want another one. I feel like it’s going down like this, like, crazy slide, and then you’re like, ‘I wanna go again.’ ‘Cause it’s so invigorating and I had great experiences,” she said.

“It’s definitely something we would consider doing again. One more time! But, like, imagine if it were twins! Oh my God. Or triplets? No, that would not happen. Doesn’t run in our family,” she added.

The Baldwins tied the knot in 2012 and have been blessed with 4-year-old Carmen Gabriela, 2-year-old Rafael Thomas and 13-month-old Leonardo Angel Charles. The couple renewed their wedding vows in June to commemorate their fifth anniversary.

Prior to the renewal of their vows, Baldwin spoke with E! News and said, “I see what I have and I’m very lucky.” The happy family recently spent Halloween together in full “Wizard of Oz”-inspired costumes. Hilaria shared their group photo on her Instagram account prior to trick-or-treating.
