Wynonna Judd

Wynonna Judd has filed for divorce from her husband, Dan R. Roach, after his arrest on charges involving sex with a minor.

The March 26 action follows Roach's arrest last week in Abilene, Texas. He faces three charges of aggravated battery against a child younger than 13. Police expect him to be extradited to Nashville, Tennessee, where the incidents allegedly took place.

Posting in a statement on her web site, Wynonna Judd says she is "devastated" by the arrest.

The couple were married in November, 2003. Dan R. Roach, her former bodyguard and road manager, has for the past month been receiving treatment for drug and alcohol addiction in a rehabilitation clinic in Texas.

Wynonna Judd, 42,  has sold nearly 30 million albums as a solo artist. She also sang with her mother Naomi in the country duo The Judds, and is the half-sister of actress Ashley Judd.
