Ali Larter has given birth to a bouncing baby boy! Both Ali and Christina Applegate announced their pregnancies on the same day over the summer, and my guess for both of them was that they were due in January – but Ali was further along than I thought! Us Weekly confirms that Ali and her husband Hayes MacArthur welcomed baby Theodore Hayes MacArthur on Monday:
Christmas arrived a bit early for Ali Larter! The Heroes actress and actor Hayes MacArthur welcomed a healthy boy early Monday morning in Los Angeles, her rep tells UsMagazine.com exclusively. Mom and child are now resting comfortably.
First-time parents Larter, 34, and Perfect Couples actor MacArthur, 33, have named their son Theodore Hayes MacArthur.
“He’s our perfect Christmas present,” the new mom and dad gush to Us.
After seven years of dating, Larter and MacArthur wed in Kennebunkport, Maine in August 2009. She was eager to start a family way back in 2007, telling Cosmopolitan: “I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow…I look forward to that time when I’m home with babies.”
Larter accidentally revealed her child’s gender in September while promoting Resident Evil: Afterlife 3D — referring to her baby-to-be as a “he” during a Fox News interview.
She added at the time: “I’m just super pregnant…Each moment I want to take off another piece of clothing.”

Christmas babies, yay! Actually, I always feel sorry for Christmas babies. Their birthdays get folded into the Christmas holiday, and I often feel like their birthday celebrations aren’t as singularly-focused as birthdays should be. In my extended family, there are many Christmas babies and it’s always a thing of “Should we send a separate birthday card and gift, or should we just package it in with the Christmas stuff?” It sucks. But there’s bad stuff with every birthday time – inevitably, my birthday was the start of the school year, so people didn’t remember it either.
Anyway, congratulations to the happy family! What do you think of the name? I think it reeks of old money and history, which is A-OK in my book. I wonder if Ali’s husband is some distant relation of President Hayes and/or General MacArthur?
