Alec Baldwin will become a proud papa for a fourth time this fall. He and wife Hilaria Thomas Baldwin are expecting their third child together.

Hilaria made the announcement on her Instagram. She shared a photo of her and Alec kissing on the streets of New York City while she carried a small, blue teddy bear for their soon-to-be little boy.

“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 32-year-old yoga instructor captioned the photo.

The couple will have a house full of babies come fall. Their oldest child together, Carmen Gabriela, is two-and-a-half years old, and their son, Rafael Thomas, is eight months old. Alec, 57, also has a 20-year-old daughter Ireland with his first wife, Kim Basinger. The family makes their home in Greenwich Village in New York.

“It's reality. I'm 57 years old. And when my son is born in July, I'll be 57 years old with two kids under two years of age," Alec said in July. “It's a very LSD-trip phase of my life. My daughter is obsessed with Peppa Pig. This is my life. There's three woman who voice the character of Peppa Pig. And she's a pig. Hello? And I'm so deep down into that crevasse right now that I have opinions on which actress is the best Peppa,"

The “30 Rock” star had plans to expand his family even more shortly after the birth of Rafael. He told People in September that he was “dying to have another child” with Hilaria.

“I love my wife more than anything. I love our family, I’m very happy. I’ve never been happier before in my life,” he said.

Alec is just as busy on screen as he is chasing two little ones around the house. He stars opposite Diane Lane in Eleanor Coppola’s (wife of Francis) debut film, “Paris Can Wait,” scheduled to premiere this year. He reunites with his “Juror” co-star Demi Moore in the movie “Blind,” and co-stars in the boxing movie, “Back in the Day,” written and starring William DeMeo.

The Oscar-nominated actor also has a part in Warren Beatty’s passion project about the elusive Howard Hughes and an affair he carried on during the later years of his life. The film reportedly finished shooting in 2014, but its director has not screened the movie anywhere yet.

He returns to the stage this summer in East Hampton, New York to star in the Arthur Miller play, “All My Sons.” The production also stars Laurie Metcalfe.
