Actor Alec Baldwin and his pregnant wife Hilaria Thomas have taken to Twitter to reveal that they'll be expecting a little baby girl this summer.

"So happy about our little girl! Thank you all for the happy wishes xoxo," the 28-year-old yoga teacher tweeted.

Us Weekly states that during an appearance on the Rachael Ray Show, Thomas shared that Baldwin really liked the name Massimo for their child. This was before they knew the gender of their child, so looks like they'll have to conjur up some new names for baby girl Baldwin.

The soon-to-be mother stated that it's probably best to just wait and see what name fits once they meet the little bundle of joy.

"I think you have to actually have to look at it once it pops out and say, 'Who are you? What is your name?'" said Thomas.

The expecting mother spoke with Us Weekly about her first pregnancy at the Academy of the Arts Lifetime Achievement Awards in New York City March 4. "At the beginning I wanted pineapple and citrus, which was not typical for me, but then you get heartburn so I had to stop that," Thomas Baldwin revealed. "I don't have really crazy cravings. I definitely eat more than I did before, but nothing too crazy."

She continued, "I'm reading a lot, although I'm learning it's not good to read too far in advance because then you freak out," she told Us. "I saw a birthing video the other day and I was like, 'That's too much information for me! I don't want to know that yet!'"

This will be the second child for Baldwin, who is already father to 17-year-old daughter Ireland with ex-wife Kim Basinger, notes E!

Baldwin & Thomas were married in June 2012 and are expecting their new baby girl sometime this summer.
