Britney Spears took part in a ‘Poo Cocktail’ challenge involving a chemical toilet, a bungee rope and the Jackass team. All in the name of promoting her new album, Femme Fatale.

Britney performed the stunt on Jimmy Kimmel Live, donning goggles before being locked into a chemical toilet and (not really) shot into the air on the end of bungee ropes.

Before her challenge, Britney was quizzed by Jackass star Johnny Knoxville who taunted her: “Are you scared of heights? Are you scared of poo-poo? What about pee-pee?”

“No, I’m not scared of poo-poo or pee-pee,” Britney replied.

The singer made her way to the chemical toilet, pausing before she entered to tell the camera:

“Hi I’m Britney Spears and this is the Poo Cocktail Supreme!”

The toilet was then bungeed into the air as Britney screamed. As the toilet spewed liquid the Jackass team made themselves retch for effect. However some viewers may have been disappointed that, on closer inspection, Britney was drenched in blue, not brown.

On landing, Britney chased the Jackass team around the field and punched Knoxville in the groin.

Having a more conventional stab at promoting Femme Fatale, Britney also performed some new songs from the album outside the Jimmy Kimmell studios, including Til The World Ends and Hold It Against Me.

But who cares about that, here’s Britney in the chemical loo again. Fake or not, it’s enjoyable viewing.
