Katy Perry was caught lip-synching during her performance of "Roar" at France's NRJ Awards over the weekend.

When she hit the stage to perform, she was out of sync with the audio and visuals. After a few minutes, the host interrupted her performance on stage and asked her if she would be willing to start over and Katy agreed.

The second time around, her vocals were live with no backing track.
