Alec Baldwin and wife Hilaria Thomas

Alec Baldwin and his wife Hilaria are set to welcome a new baby into the family, the actor's representative confirms to TODAY. Hilaria is pregnant with the couple's first child, due late this summer.

"It was a surprise, it was a wonderful surprise," Hilaria told "Extra," where she is a special correspondent. The couple broke the news with the program, and even explained exactly how they found out a baby was on the way.

Alec recalled: “There’s a scream I heard, which is a scream normally reserved if there’s a spider in the house, not exaggerating. Normally I will be reading a book, we're in the country, it's quiet, some time to really relax and unwind and sometimes once a month you hear 'ahhh  Alec, Alec!'  I come upstairs and there’s a spider on the wall, so then I hear that scream again, but it was not a spider."

Hilaria continued, “It was followed by 'I’m pregnant, I'm pregnant,' he runs up the stairs and I'm holding (the pregnancy test) and showing it to him.” 

“You can make as many jokes as you want, but it really is the most amazing thing, I’m lucky," Alec said of the news. As for Hilaria, she's feeling good and starting to plan for the new baby. “Now, I’m showing, it’s getting to be much more, like OMG this is actually gonna happen, now we can start the nursery, the everything, the dreaming," she told Extra.

Hilaria and Alec wed in New York in June 2012. He has one daughter, Ireland, from his previous marriage to actress Kim Basinger.

Baldwin's NBC comedy, "30 Rock," ended its seven-season run in January.
