Video: 'Are you a double?' - Rita Ora performs on The Voice Germany but isn't recognised by the judges

British artist and UK The Voice coach Rita Ora made a surprise appearance on Germany's version of The Voice, but it took a while for the judges to click. 

Ora looked to be a contestant, singing her hit song Your Song in a blind audition, to which all the judges turned their chairs around to see the performer. 

"I'm a 26-year-old aspiring musician from London," she tells them. "How did I do?"

"It sounded almost like the original," judge Mark Forster says.

When she tells them she is the original artist of the song, judge Yvonne Catterfeld says, "Uou're kidding us. Are you a double?"
