It’s a bouncing baby boy!

Ali Larter and her writer/actor husband Hayes MacArthur welcomed their first child earlier this week, her rep confirms to PEOPLE.

Their son, reportedly named Theodore Hayes, arrived early Monday morning, Dec. 20.

Larter, 34, let slip she was having a boy midway through her pregnancy.

She also made sure to have some fun while she was expecting, reveling in desserts such as strawberry shortcake and saying last summer that she was “bring[ing] on the Sprinkles cupcakes, pizza, pasta. I’m loving it!”

She celebrated the baby with friends including Amy Smart, Busy Philipps and Nicole Sullivan at a shower in October.

Larter told PEOPLE during her pregnancy that impending motherhood put things in a whole new light.

“To feel this life growing inside of me grounds me every day and really puts things into perspective about what’s important in life,” she said. “It really is your health and your family.”

Congratulations to them! I love the name. It’s so cute!

I hate that my first thought was about the chipmunk, though.

klutzy_girl: Ha, well if you don’t like the chipmunk, you can always think think of our 26th president! 🙂

Theodore Hayes MacArthur. It’s nice. Sounds like a future president! 🙂

LOL @klutzy_girl! At least Theodore was the cuddliest Chipmunk! 😉 PS, Love your screen name!

Niko on

Wow, one of those boy names (Bartholomew, Julius, Irving, Lazarus, etc) that parents don’t name their kids anymore. Glad to see “Theodore” make a comeback! Congrats Ali and Hayes!

Kristin on

Oooooh, love the name! Doesn’t Bryce Dallas Howard have a Theo too? I really like it.

I’m another who was sure that baby was never coming out! So glad he’s made his arrival, just in time for Christmas.

Maddie on

Wow finally! It seems as though she’s been pregnant forever.

I love the name Theodore. Those classic names are just great.

fuzibuni on

Nice name!! Theodore is number one on my list of favorite boys names.
And to pair it with Hayes MacArthur is pure perfection.

Ale on

I had a feeling the little boy would either be a Jr, or be named after the father in some way!

auroramia on

I agree with fuzibuni. It’s a brilliant name!

If I have a daughter I always liked the name Theodora. I guess I could be more trendy an just name her Theyodorlynn Grayce.

All snark aside, I love baby Theodore’s name. I’m sure he’s a beautiful boy. Congrats to Ali and Hayes.

soph on

It doesn’t sound like the name of a future president, but one that lived in the past. It’s great. Theodore has nice nickname possibilities too.

Mallory on

You know, I usually don’t like most of the older, classic names, but I really like Theodore. And especially the nickname Theo!

Congrats to Ali and Hayes and their families!

The whole name Theodore Hayes MacArthur is very distinguished and has a wonderful ring to it. Having said that, I hope she calls him Theo.

lol on

she is gorgeous and congrats!!!! love that name! can call him theo~~~

betsyboo on

I hope they call hiim Ted or Teddy, that would be cute. She is such a beautiful girl, but that Missoni dress is horrible. Missoni knits are about the ugliest things I have ever seen women wearing. Doesn’t matter, Ali is one of the most beautiful women I’ve ever seen, and I know she and her hubby will have a beautiful baby boy.

Judy on

Congrats, Ali! A beautiful mom, no doubt the baby will be beautiful too!!!

mom of theo on

We love the name Theo! It’s our beautiful boy’s name!
