Katy Perry was left red-faced at the weekend after she was cut-off midway through a performance in France.
The 29-year-old had been performing her latest hit, Roar, at the NRJ music awards in Cannes on Saturday when she was suddenly interrupted and told to start again by one of the award hosts.
"I'm sorry to stop all your energy, I prefer you to be the best," he told the pop star on stage, which drew boos from the crowd. "If you don't mind, we can restart. We had a little problem with the sound."
Although clearly embarrassed, Perry carried on with her live performance without fuss.
Footage of the interrupted performance has gone viral online, leading some to question whether Perry had been lip syncing.
However, event organisers claim the botched performance was due to a technical difficulty.
"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," they said in a statement.
