Jason Derulo also appeared last night on American Idol, wowing the crowd with some fancy footwork and a polished vocal performance.
There was further interest in the performance as Kara DioGuardi was the one who initially signed Derulo to a record label, adding a certain amount of pressure to the appearance.
However Derulo seemed to pass the test with flying colours. â€œThat was absolutely great. Well done,â€ Simon told Jason after his high energy performance.
