Katy Perry was performing her hit song "Roar" recently on a French music awards show and the track that she was lip-syncing to was a bit off.

OK, it was really, really off. It was so far off that it seemed like she was singing a completely different song all together.

Instead of just letting her get away with it, the host of the show called Perry out on stage and made her start over and sing it again.

It sure sounded different the second time around. Hmm. Strange.
