Katy Perry's NRJ Awards Mixup

“I Kissed A Girl” singer Katy Perry shines in a white Dolce & Gabbana suit and ruby red lips on the NRJ Music Awards (France’s foremost music awards) red carpet at the Palais des Festivals in Cannes, France on Saturday (January 17).

During the ceremony, the 24-year-old chanteuse was mistakenly named winner of Best International Song — an award actually meant for Rihanna’s “Disturbia.”

Katy did legitimately win the Best International Album award, and received an apology for the error at the end of the show from host Nikos Aliagas.
