Actress Ali Larter shows off her bouncing baby boy

Actress Ali Larter has been showing off her brand new baby boy in the pages of Us Weekly magazine! The former Heroes star gave birth to son Theodore Hayes MacArthur — her first child with hubby Hayes MacArthur — on December 20 in Los Angeles.

Theodore weighed 7 pounds, 3 ounces at the time of his birth.

Ali says the baby’s arrival was a bit dramatic.

“During the L.A. mud slides, our street was closed,” said Larter, 34.

“Four hours after the fireman opened it, I was in labor!

“It’s incredible to look at this little guy and think he grew inside of me.”
