Wilson Brothers Sued Over Pap Attack

Andrew and Owen Wilson are collaborating on a new project together -- they're co-defendants in an assault case.

A paparazzo is suing the pair over an alleged fight that went down in Santa Monica on December 5, 2008. The photog, Clint Brewer, claims he "sustained severe bodily injuries, a portion of which are permanent."

According to a lawsuit filed last week, Brewer says he "was walking up the stairs and was pushed in the back by" Owen Wilson. Brewer claims he has suffered medical expenses in the amount of $3,251.10 and general damages in the amount of $500,000.
