LOS ANGELES (AP) - ''Jackass'' star Johnny Knoxville is officially single. A judgment finalizing the dissolution of the actor's 12-year marriage to Melanie Lynn Clapp was entered in Superior Court last Thursday, according to court documents.

Messages left Monday for Knoxville's publicist and attorney were not immediately returned. Knoxville, whose birth name is Philip John Clapp, filed for divorce last July citing irreconcilable differences. The couple separated in July 2006.

Knoxville, 37, was seeking joint custody of the pair's 12-year-old daughter. Custody arrangements and child support were not included in last week's judgment.

Knoxville's screen credits include ''The Ringer,'' ''The Dukes of Hazzard'' and the ''Jackass'' stunt movies.
