It's a boy!
Hilaria and Alec Baldwin took to Instagram to announce they welcomed their third child together on Monday night.
"We are so pleased to introduce you to our new baby, Leonardo Ángel Charles Baldwin," the proud mama captioned a shot of herself cradling her newborn in her arms in her hospital bed. "It was such a special day bringing him into this world."
Alec also took to his Instagram to regram his wife's pic, as well as a shot of himself holding his baby boy with a huge smile on his face.

"Leoncito!!!!!" he captioned the shot, adding the Spanish diminutive to his son's name.
Little Leonardo has three older siblings; sister Carmen Gabriela, 3, 14-month old brother Rafael Thomas, and 20-year-old Ireland, who Alec shares with ex-wife Kim Basinger.
"I love my wife more than anything," he gushed to PEOPLE magazine last year. "I love our family, I'm very happy. I've never been happier before in my life.”
