Justin Bieber enlists Jersey Shore's The Situation and Pauly D for two not-so-funny promo clips for the Pop sensation's upcoming 3D film. The Situation gives a guide to "pimpin'" which we assume refers to prepubescent boys taking tweenage girls to see the film just in time for Valentine's Day. Pauly D seems to have caught Bieber fever and ditches the hair gel.

Kim Kardashian and Khloe Kardashian, Angelina Jolie, Diddy and Jay Leno are amongst other the celebrities appearing in upcoming promo clips for the 3D documentary film which he premiered in Toronto yesterday.

Never Say Never hits theatres February 11.
