Chris Pontius to Divorce -- 'Jackass' Star's Marriage -- The Party's Over

Chris Pontius -- aka "Party Boy" from "Jackass" -- is getting divorced ... TMZ has learned.

According to the docs filed last week in L.A. County Superior Court, Pontius' wife Claire Nolan (pictured above) is requesting the split. 

36-year-old Pontius married Nolan back in 2004. They have no children together.

UPDATE: In the docs, Nolan cites "irreconcilable differences" -- and claims the two officially separated back in 2009.
