It's finally a boy for Alec Baldwin!

The actor and his wife Hilaria welcomed their second child together this week, a little boy named Rafael Thomas Baldwin.

HIlaria confirmed the happy news via Instagram, posting a gorgeous snap of Rafael's tiny hand in hers.

The newborn Baldwin will be a little brother to 21-month-old Carmen Gabriela, and also to Alec's 19-year-old daughter Ireland, born during his first marriage to Kim Basinger.

Alec and Kim split back in 2002, and the actor remarried in 2012. There might be a 21 year age gap between himself and his second wife, but Alec had no reservations about becoming a father again late in life – and was thrilled to find out HIlaria was expecting a boy.

"The day that I told him he carried a football around for an hour afterwards," the 31-year-old yoga teacher said of her husband's sweet reaction to the news.

Alec and Hilaria revealed they were expecting again back in January with a beautiful family beach snap, showing little Carmen touching her mum's growing belly. The photo was captioned, "2015 is going to be very exciting as we are thrilled to announce we are expecting another little addition to our family! (tadasana) #yogapostureoftheday #baldwinbabybump"

Speaking to reporters shortly before Rafael's birth, Alec said the experience of becoming a dad again was "surreal" to him but that he felt "blessed, very blessed" all the same.

It has been a whirlwind year for the father of three, with 19-year-old Ireland entering rehab back in April with her parents' support. The teenager openly discussed her decision on Twitter, laughing off reports that she was forced to check in due to too much "intensive partying."

Ireland also praised her parents and Hilaria for helping her throughout the process, saying, "Both of my parents, step mom, carmen, and friends… were all there for me at all times. Little do you know… We've never left each other's sides."

Congrats to Alec and Hilaria on their new arrival!
