Johnny Knoxville toasts his 'Wild and Wonderful Whites' with Kid Rock, The Situation

Johnny Knoxville would know a good hoedown when he saw it, so naturally the "Jackass" host-turned-actor would be an appropriate host for an authentic backyard barbecue.

Host he did tastemakers and celebs, with Tribeca Film and American Express, to mark the release of "The Wild and Wonderful Whites of West Virginia," a documentary that Knoxville executive-produced about the intense rural White family. 

American-made musician Kid Rock stopped by to chomp on a cigar and chat up former fling Jamie King. Footage was screening and a live performance offered from White family patriarch Jesco, David Alan Wade and film composer Deke Dickerson. 

Actors Bryan Greenberg and Michael Rosenbaum enjoyed spiked punch and cornbread at the fete, though all eyes were on "Jersey Shore" breakout Mike "The Situation" Sorrentino.

He of the iron abs came, snacked on barbecue chicken and spiked iced tea, and chatted up partygoers including Brittny Gastineau.
