Baby Camden Quinn Schaech was born in L.A. at 2:50 a.m., Schaech's rep told Us Weekly. He weighed in at 7 pounds, 15 ounces, and measured 19 inches.
Coincidentally, the 44-year-old actor's character on Showtime's "Ray Donovan" also has a new baby on the show.
"In the second episode, I carry the baby over to Liev and tell him to smell her head. The line was, 'Smell her hair,' but she didn't have any hair, so I was trying to make Liev laugh. He came to me after the first take and said I should support the baby at the back of the neck, so the head doesn't move so much," Schaech explained.
This is the first child for both Schaech and his wife, 29. The couple married this summer in a secret ceremony. He was previously married to actress Christina Applegate and to country singer Jana Kramer.
