Singer Katy Perry battled technical difficulties while performing at the NRJ Awards in France this weekend (14-15Dec13).
The pop superstar took to the stage to perform her hit single Roar, but had to stop midway through the set because she was out of sync with the audio and background screens.
Running onto the stage to alert Perry to the issue, the host asked her to "restart" because they "had a little problem", and added, "I'm really sorry to stop all your energy."
Despite the mishap, Perry had reason to celebrate at the prizegiving - she was a double winner at the ceremony, which was held at the Cannes Festival Palace in the south of France, as she scooped the International Female Artist of the Year title and landed International Song of the Year for Roar.
NRJ has issues the following statement: "Katy Perry was singing live at the NRJ Awards Saturday night in Cannes, but regrettably the wrong mix has been played accidentally which over-rode Katy's live vocal feed on-air at the beginning of her performance of 'Roar. TF1 & NRJ would like to apologize to NRJ double award winner Katy Perry for this technical problem beyond our control."
