Ali Larter and Husband Welcome a SonAli Larter and husband Hayes MacArthur have another reason to be joyful this holiday season: the birth of their son! "He's our perfect Christmas present," the couple told Us Weekly.

The 'Heroes' actress and MacArthur, who appears in NBC's upcoming 'Perfect Couples,' welcomed their first child, Theodore Hayes MacArthur, on Monday.

The couple, who married in 2009, announced Larter's pregnancy in July.

The actress, who dated MacArthur for seven years before they became engaged, told Cosmopolitan, "Since I was 15 years old, all I wanted was to find the guy I was going to marry ... And then ... I got blindsided. [Hayes] showed me the way, and all was right. This is how it's supposed to be."
