Justin Bieber is a regular on the late night circuit but we're kind of over him just sitting on a couch and steering the conversation away from his love life.
He made an appearance on James Corden's late late show and we learned a lot from it.
Justin Bieber has a diamond encrusted Cartier Bracelet
He never wears the same underwear twice (and he gets a lot of Calvin Klein underwear).
He can do a rubik's cube on command.
Justin also spilled the beans on whether or not he listens to his own music when he makes love and whether or not he kisses before marriage.
