Alec Baldwin finally has a reason to calm down.
The often-angry actor is all smiles at the moment because his wife just gave birth to the couple's third child.
It's a boy and Hilaria Baldwin was feeling well enough after giving birth that she shared an Instagram photo of herself and the newborn soon after welcoming him into the universe.
This is what she wrote as a caption to the sweet snapshot:
"We are so pleased to introduce you to our new baby, Leonardo Angel Charles Baldwin. It was such a special day bringing him into this world."
The Oscar and Emmy-nominated actor also Tweeted a few details about his son's birth, including with his message a link to the above image.
"Leonardo Angel Charles, September 12, 6:51pm, New York City," Baldwin wrote on social media.
The famous couple got married in June 2012.
That was just over four years ago, but they haven't wasted any time at all when it comes to making many children together.
Alec and Hilarious are also parents to a three-year old named Carmen and a 14 month-old named Rafael.
The former 30 Rock star is also dad of model Ireland Baldwin, whom he shares with ex-wife Kim Basinger.
A yoga instructor, Hilaria Baldwin often fills up her Instagram feed with photos of herself doing various poses... while lying alongside one of her adorable munchkins.
In March, the Baldwins announced they were expecting their third child together, less than a year after welcoming little Rafael.
"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 picture of the couple kissing.
She added that it would be a "little boy" who would arrive "this fall."
And she was right!
Of her three-year old daughter, Hilaria told Us Weekly in June of 2015 that she couldn't have been more excited to have a little brother.
"She wants to kiss him, hold him, sing to him and feed him food she can't eat," Baldwin said at the time. "She's a good big sister."
And now she has TWO little brothers to kiss, hold, sing to and feed. So precious!
We send our hearty congratulations to this newly-expanded family, while we also send our best wishes.
With three children under the age of four, we're guessing they'll need them!
