The Christmas of 2012 will always be a memorable one for Alec and Hilaria Thomas Baldwin.

Not only was it their first as a married couple, but days before the celebration, they found out they were expecting a baby.

“It was something that we both wanted — I don’t want to say it was a surprise and we didn’t want it — we were very excited when we found out,” Thomas Baldwin, who is due in late summer, said Friday on the Rachael Ray Show.

“But we just got married in June … so it was a really nice Christmas present.”

With Thomas Baldwin busy satisfying her frequent fruit cravings, the Orphans actor, 54, has been preparing for his upcoming role as doting dad.

“At this point, before the baby is born, he thinks he’s going to be Mr. Mom,” the expectant yoga instructor, 28, shares. “We’ll see if at 3 o’clock in the morning when the baby is screaming and we need to change the diaper if he’s going to be Mr. Mom at that point.”

Although Thomas Baldwin has no preference whether she welcomes a son or daughter, her bets are on a baby boy. Her sneaking suspicions will be confirmed “in a few weeks” when the parents-to-be plan to find out the sex of their little one.

“Somebody gave me some really great advice which was, you’re going to find out eventually,” Thomas Baldwin explains. “It’s going to be a surprise eventually, so why not have the surprise sooner? It’s like Christmas sooner!”

And if her guess on the early gift is true and the couple are indeed expecting a son, Thomas Baldwin may have to negotiate on the baby names.

“[Alec] had the idea for Massimo the other day. It’s a lovely name, I just don’t know,” she says. “That’s a very big name for a very little baby.”

Explaining that they “have a different idea almost every single day,” Thomas Baldwin hopes to wait until baby boy’s birth to make the final decision. “I think you actually have to look at it once it pops out and say, ‘Who are you? What is your name?'” she says.
