HOLLYWOOD, Calif. — Johnny Knoxville has finalized his divorce.

The 38-year-old "Jackass" star and his ex-wife, Melanie Lynn Clapp, put the finishing touches on their agreement last Friday in a Los Angeles court, with Knoxville agreeing to pay $6,000 a month in child support for their 13-year-old daughter, Madison.

While the former couple agreed to split their personal community assets evenly, Clapp will receive royalties from the "Jackass Concept" franchise and the Knoxville film "Dukes of Hazzard."

Knoxville and Clapp, who tied the knot in May 1995, will share joint custody of their daughter.

The ex lovers separated in 2006 and filed for divorce the following year.

Knoxville, whose real name is Philip John Clapp, was detained earlier this year at Los Angeles International Airport when authorities discovered an inert grenade in his carry-on luggage. He later apologized for the incident.
