Britney Spears Invades 'Jimmy Kimmel' With 'Jackass' Sketch, Performances

On last night's (Mar. 29) "Jimmy Kimmel Live," Britney Spears went above and beyond musical guest duties, starring in a sketch called "Poo Cocktail Supreme" alongside the "Jackass" crew.

Spears didn't shy away from her goofy side during her appearance, showing off her new (and less-than-permanent) Kimmel tattoo with the host -- and later joking, "You're getting on my nerves."

Continuing the playful streak, Britney's big moment was her collaboration with "Jackass" star Johnny Knoxville, who presented what he joked was an out-take from "Jackass 3D" during his appearance on last night's "Kimmel." Those familiar with the "Jackass" brand will be less-than surprised to hear that the stunt was deemed "Poo Cocktail Supreme." Knoxville's revenge is (probably) forthcoming, per Spears' tweet.

After all the fun and games, Spears hit the "Jimmy Kimmel Live!" stage to perform both "Femme Fatale" singles, "Till The World Ends" and "Hold It Against Me." And like any proper pop diva, there was a wardrobe change between the two performances.

Spears' "Femme Fatale" saw a release yesterday (Mar. 29) -- the same day the singer's San Francisco concert aired on "Good Morning America," where she announced a summer tour.

We've seen Britney shine with humor before, most memorably during her multiple "Saturday Night Live" hosting duties.

Perhaps we'll see the singer taking over the "SNL" stage yet again, but for now, what did you think of Britney's antics on "Jimmy Kimmel Live"? Tell us in the comments below!
