They're sure expanding their brood at a rapid rate!

Alec Baldwin and wife Hilaria are expecting their third child, they revealed in an adorable photo announcement today. They are already parents to daughter Carmen, 2, and son Rafael, 8-months-old, and the actor has daughter Ireland, 20, from his marriage to Kim Basinger.

"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 fall," the yoga instructor captioned a sweet snapshot of the pair kissing and holding a blue teddy bear.

"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," the 30 Rock star dished to People this past September.

Congrats Baldwins!
