Backstreet's Bum

Even the most famous male pop stars get embarrassed sometimes.

MTV's Chris Connelly chatted with Backstreet Boy, Howie, about a rehearsal that left Howie a bit embarrassed and his dancers hysterical.

When the band was rehearsing a part in the show where they "fly" into the audience, Howie's pants fell down as he did a flip.

Howie was the lucky one though. Kevin, also in the Backstreet Boys, had a pant-slip too. Unfortunately for Kevin, his pants fell down during a concert, the first one of the tour in North Carolina. The group's 39-city tour is sold-out.
