Three’s company, right?

Congratulations are in order for Hilaria and Alec Baldwin, who welcomed their third child together on Monday, Sept. 12, at 6:51 p.m. in New York City. The couple named the adorable baby boy Leonardo Ángel Charles Baldwin, officially making their first two children, Carmen Gabriela, 3, and Rafael Thomas, 1, brand new older siblings. Alec also has a 20-year-old daughter, Ireland, with Kim Basinger.

Hilaria confirmed the arrival of their little boy in an Instagram post. "We are so pleased to introduce you to our new baby, Leonardo Ángel Charles Baldwin. It was such a special day bringing him into this world," she wrote in the caption to a photo of herself cradling baby Leonardo.

Earlier this year Hilaria shared the exciting news of her pregnancy with an epic Instagram of herself and Alex kissing on the streets of New York. “Ireland, Carmen, Rafael, Alec and I are excited to share with you that we are going to have another addition to our family. A little boy coming this well,” she wrote as she carried a too-cute blue teddy bear to signify the baby’s sex.

Baldwin dished on his love of parenthood in September 2015, telling People, “I’m dying to have another child with my wife… I love my wife more than anything. I love our family, I’m very happy. I’ve never been happier before in my life.”

Over the course of her pregnancy, Hilaria proudly used social media to flaunt her then growing baby bump, and to explain why yoga, a favorite pastime of hers, helped her get through the experience.

Getting towards the end of pregnancy, it is hard to stay fit. I worked out every day I was pregnant with Carmen, less with Rafa, and with this one....I REALLY have to get creative and make time. One of the things that I love about yoga is that all you really need is your body, so you can do it anywhere at anytime! I am working on getting a YouTube channel going so I can post videos for you. Probably I will start after the baby is born. As I have said before, I am a total failure when it comes to technology, so bear with me.
