It's a boy for Kevin Costner!

The "Dances with Wolves" star and wife Christine welcomed little Cayden Wyatt Costner at 10:30 p.m. Sunday at an undisclosed Los Angeles area hospital.

Costner's publicist said, "Both mother and son are doing well."

The bouncing boy weighed seven pounds, 14 ounces and has dark hair.

Costner married 33-year-old Christine in September 2004 at his sprawling ranch home in Colorado.

Baby Cayden is the fifth child for Costner and the first for Christine.
