Kevin Costner and his wife, Christine Baumgartner, welcomed a baby boy on Thursday night in Los Angeles, the Dances with Wolves Oscar winner's publicist has announced.

Hayes Logan Costner weighed 8 lbs., 15 oz., upon arrival.

Costner recently told the Associated Press that the name Hayes was "a cowboy character" in a Western movie he soon plans to make, and that it is "a great Western name."

Costner, 54, and Christine, 34, announced her pregnancy in November. They were married in 2004.

The couple's first son, Cayden Wyatt, was born in May 2007. Costner also has four children from previous relationships.
