Ali Larter, who starred on "Heroes," debuted her son Theodore Hayes MacArthur in the new issue of Us Weekly.
Theodore is the 34-year-old actress' first child with her husband, actor Hayes MacArthur, who currently stars on NBC's new comedy "Perfect Couples."
"During the L.A. mud slides, our street was closed," Larter said of the day she had her son. "Four hours after the fireman opened it, I was in labor!"
Larter's blue-eyed baby weighed 7 pounds, 3 ounces at birth and Larter is still overwhelmed by the 'little guy.'
"It's incredible to look at this little guy and think he grew inside of me," Larter said.
Larter and MacArthur got married in Kennebunkport, Maine in August 2009.
