Los Angeles - Alec Baldwin and his wife Hilaria have welcomed a baby boy into the world.
The actor's 31-year-old yoga instructor wife announced the birth of their son Rafael Thomas on Instagram by posting a picture of the baby's tiny hand.
She captioned the image: "We are happy to announce the birth of Rafael Thomas Baldwin."
The birth comes 22 months after the couple - who tied the knot in 2012 - welcomed their first child, a daughter named Carmen.
Hilaria documented this pregnancy with pictures of her growing bump on Instagram, keeping fans updated on her progress.
However, the impending birth has not stopped Hilaria from continuing with her busy lifestyle, which has recently included penning a fitness and wellness book.
Meanwhile, Alec - who already has a 19-year-old daughter, model Ireland, from his marriage to actress Kim Basinger - revealed earlier this year just how much he was looking forward to the birth of his baby boy.
He said: "(I'm) blessed, very blessed. We're having the baby and that's almost surreal to me."
Hilaria also admitted she was thrilled Carmen will have a brother close to her age.
She said: "We're really excited to have another baby! We definitely wanted Carmen to have a sibling near her age."
