Taking to Instagram, the actor published a romantic shot of him and his yoga instructor wife sharing a tender kiss on the streets of New York, as the pregnant beauty held a blue teddy bear between them.
“Ireland, Carmen, Rafael, Hilaria and I are excited to share with you that we are going to have another little addition to our family. Another little boy coming this Fall,” the 30 Rock actor lovingly penned.
The couple, who married in 2012, are already the proud parents to two-year-old daughter Carmen and eight-month-old son Rafael.
Alec shares 20-year-old daughter Ireland Baldwin with his ex-wife Kim Basigner.
Despite having a young family on her hands, Hilaria is still as determined as ever to keep up her yoga and has risen to fame thanks to her Instagram account, which documents her freakishly flexible poses.

"I wanted to do a pose each day. I've now realised that it's really hard to think up a new one every day! But I made a promise and I'm going to keep it. The best poses are the more spontaneous ones," the mother-of-two explained to Hello! Magazine.
And since welcoming her children into the world, Hilaria has even started to incorporate them into her routines.
Meanwhile 57-year-old Alec has never shied away from the fact he wants to have a big family with Spanish-born Hilaria, 32.
“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,” he told People last year.
Looks like his wish is coming true! Congratulations to the happy and very cute family.
