Britney's Embarrassing Stage Show

Britney Spears says she'll never forget her worst concert performance - and it makes her work even harder to make sure she never repeats it.

She recalls, "I had on a flight suit that my dancers were supposed to pull off me. There I was, in front of thousands of people and they were pulling and tugging on me - and it wouldn't come off.

"If that wasn't bad enough, later that same show, I slipped on a cupcake that someone had thrown onstage."
