britney jackass Britney Spears steps up for 'Jackass' stunt on 'Jimmy Kimmel'Britney Spears must really want to sell some albums. The performer, whose latest —
“Femme Fatale” — just dropped, performed on “Jimmy Kimmel Live” Tuesday (March 29) evening.

But the highlight of the show was a supposed outtake from “Jackass 3-D” brought to the show by guest Johnny Knoxville. In it, Spears appears to step up for one of the crew’s signature stunts, the “Poo Cocktail Supreme.”

For those of you who haven’t seen the movie, we’ll describe it before you press play below. In the stunt, a volunteer is locked inside a port-a-potty which is attached — by bungee cord — to a crane. Volunteer inside, the crew releases the bungee, causing the port-a-potty to vault into the air and bounce. And bounce. And bounce. The contents of the tank are, of course, thrown all over the volunteer.

In the original movie, Steve-O ended up covered in unmentionable filth, inspiring some of his grossout buddies to vomit. Britney, on the other hand, seems to have escaped with only a little blue liquid splattered into her weave.
