The pair, who are already parents to Leonardo, 1, Rafael, 2, and Carmen, 4, will welcome baby number four this coming spring. (Alec, 59, also has a 22-year-old daughter, Ireland, with ex Kim Basinger.)
Hilaria shared the good news on Instagram Friday with an adorable family photo.
“Our Baldwinitos are getting a new teammate this spring,” Hilaria wrote in the caption. “I’m gonna make them a special cake to tell them if it’s a boy or a girl...I’ll post it tomorrow midday 😘. We are so excited!”

Hilaria, 33, has expressed her desire for more children in the past.
In October, she toldAccess Hollywood, “For some reason, right after I deliver a baby, I want another one.”
She added, “I feel like it’s like going down this, like, crazy slide, and then you’re like, ‘I wanna go again.’ ’Cause it’s just so invigorating and I had great experiences.”
Congrats to them both!
