Alec Baldwin is a daddy again.

The "30 Rock" actor and his wife Hilaria Baldwin are the proud parents of a baby boy. The couple shared the exciting news on social media Wednesday and also revealed the newborn's name.

"We are happy to announce the birth of Rafael Thomas Baldwin," the mommy of two captioned an Instagram photo of her holding hands with her newborn son.

Additional birth details were not immediately available.

The couple, who tied the knot in 2012, also have 21-month-old daughter Carmen Gabriela, and Alec is also dad to Ireland, his 19-year-old daughter with ex-wife Kim Basinger.

In January, the couple announced they were expecting their second child together. Since announcing her pregnancy earlier this year, Hilaria, a yoga instructor, has been regularly uploading photos and also posted a video of her son moving in her belly.

"As the time gets closer, I think I'm gonna miss toting my little ambiguity around ... tho can't wait to meet him," Hilaria captioned a recent shot of her bump.
