Alec and Hilaria Baldwin have announced the birth of their baby boy, Rafael Thomas Baldwin.

Hilaria posted an instagram to announce the birth

57-year-old Baldwin already has a 19-year old daughter named Ireland with Kim Basinger and a 21-month-old daughter named Carmen. 

31-year-old Hilaria, who is a yoga teacher, said Baldwin was delighted when she broke the news of her pregnancy. "The day that I told him he carried a football around for an hour afterwards," she said.

The couple met in 2011 when Baldwin greeted Hilaria at a restaurant and handed her his business card with his mobile phone number written on the back.

They went out together for a year and married at St Patrick's Old Cathedral in New York. Guests included Alec's brothers Stephen and Billy Baldwin, Tina Fey and Woody Allen. Alec's daughter Ireland was the maid of honour.
