Trace Adkins' wife files for divorce

The wife of country singer Trace Adkins has filed for divorce and is asking for custody of their three children.

Adkins and his wife, Rhonda, have been married for nearly 17 years. She filed for divorce on Monday in Tennessee's Williamson County, where they live outside of Nashville, citing "irreconcilable differences."

A publicist for Adkins said Thursday, "Trace and Rhonda are united in ensuring that their children's interests come first. They thank everyone for respecting their privacy as they work through this personal matter together."

Adkins went into rehab in January after consuming alcohol during a weeklong Country Cruising cruise and reportedly getting into a fight with an impersonator on the ship. The 52-year-old "Celebrity Apprentice" winner canceled his remaining performances on the cruise, but had recently performed on the Grand Ole Opry.

TMZ reports that Adkins left rehab after two weeks to tend to his ailing father, who died in early February.
