Teen actress Emmy Rossum learnt an important lesson on the set of THE PHANTOM OF THE OPERA - always check your backside isn't on show before leaving your dressing room.

The 18-year-old beauty - who plays CHRISTINE in the movie version of the stage show - was left red-faced after realising she'd filmed an entire scene with her rear exposed.

She recalls, "I got back to my dressing room and realised the whole back of my dress had been ripped off and everyone had been watching my bare behind for the past hour.

"It taught me a lesson that in future I should always check my butt."
