KP was performing at the NRJ Music Awards in Cannes last weekend and apparently, she was mouthing the words to her song, “Roar,” but the words coming from the speakers didn’t appear to match what she was saying. Oops!

It was previously reported that the singer experienced technical difficulties at the award show, but still…she seemed pretty shaky when the song restarted.

According to Radar Online,  “Katy Perry sang live during the NRJ Music Awards in Cannes on Saturday night, but unfortunately a bad soundtrack was accidentally launched, taking over the live performance of Katy at the beginning of the delivery tube of the ‘Roar.’”

Oh. A bad soundtrack. Let’s go with that.
