Johnny Knoxville Pulls the Plug on Marriage

TMZ has obtained documents, filed today in Los Angeles County Superior Court, in which Knoxville (real name P.J. Clapp) cited "irreconcilable differences" in his nearly twelve-year marriage to wife Melanie.

We're told there is no prenup and Knoxville will pay spousal support. He's asking for joint custody of the couple's only child, 11-year-old daughter Madison.
