Alec and Hilaria Baldwin on Monday were blessed with their third child — son Leonardo Ángel Charles Baldwin — at 6:51 p.m. in New York City, according to posts on their social media accounts.

The latest addition to the family comes a little more than a year after Hilaria gave birth to their second child, 14-month-old Rafael Thomas. The couple’s oldest child is Carmen Gabriela, their 3-year-old daughter. The "30 Rock" actor is also the father to Ireland Baldwin, 20, his daughter from his previous marriage.

Alec, 58, and Hilaria, 32, who got married in 2012, announced that they were expecting their third child together in March.

“Ireland, Carmen, Rafael, Alec, and I are excited to share with you that we are going to have another addition to our family,” Hilaria captioned an Instagram photo of the couple kissing. “A little boy coming this fall.”

The yoga instructor also shared pictures of her growing baby bump through her pregnancy.

In June 2015, she told Us Weekly that Carmen was a great older sibling.

“She wants to kiss him, hold him, sing to him and feed him food she can't eat,” Hilaria told the publication. “She’s a good big sister.”
