There’s a new boy in the Baldwin bunch.

Alec and Hilaria Baldwin have welcomed their second child together, a son, the proud new parents confirmed Wednesday on social media.

“We are happy to announce the birth of Rafael Thomas Baldwin,” the new mama captioned an Instagram photo of her holding hands with her newborn baby, who has mom’s maiden name for his middle.

In January, the couple announced they were expecting a sibling for 21-month-old daughter Carmen Gabriela by sharing a photo of the growing family — and Hilaria’s baby belly — on the beach.

“The sun has set on 2014. 2015 is going to be very exciting as we are thrilled to announce we are expecting another little addition to our family!” Hilaria, a yoga instructor, wrote alongside the snapshot.

The following day, Hilaria took to Instagram once more to hint at the sex of their baby on the way.

“So we have an announcement to make … can you guess??” she teased, sharing a photo of the family’s shoes, including a pair of navy baby loafers.

Since the announcement, Hilaria has been keeping her followers in the loop throughout her pregnancy with regular updates on her growing baby belly. “As the time gets closer, I think I’m gonna miss toting my little ambiguity around … tho can’t wait to meet him,” she captioned a recent shot of her bump.

Alec, 57, is also dad to Ireland, his 19-year-old daughter with ex-wife Kim Basinger.
