Costner welcomes baby boy

Kevin Costner and his wife have announced the arrival of their second child.

Hayes Logan was born on Thursday night in Los Angeles and weighed 8lbs 15oz, the actor's publicist confirmed to MSNBC.

Costner, 54, and his 34-year-old wife Christine Baumgartner already have one-year-old Cayden. The Dancing With Wolves star also has four other children from previous relationships.

The couple announced the pregnancy in October, revealing that they were "ecstatic" by the imminent arrival.
