Katy Perry caught terribly lip syncing! Katy Perry Tue-17-Dec-13 17:53 Share this By Steph Monks Katy Perry was really, really, reeeally badly lip syncing on live TV! She was performing 'Roar' at the French music awards and the track in her earpiece she was lip syncing to was different to the track that the audience could hear. She had to be interrupted and told to start again from the top. EMBARRASSING! See the video below!
