March 13: Katy Perry took a tumble while dancing on Monday's episode of American Idol – exposing herself to fellow judges Lionel Richie and Luke Bryan.

The 32-year-old pop star was prancing around for contestant Michelle Susset, a 22-year-old waitress from Miami with roots from Venezuela.

Michelle had done an energetic Spanish number that got the whole panel grooving.

But Katy toppled over in her tight dress and heals, exposing her crotch.

'Oh dear god…there are things a man can't unsee,' exclaimed Luke as Michelle received a golden ticket.
