The finale included performances by Adam Lambert and UK singer Jesse J. Psy made a cameo to perform his latest single, “Gentleman,” and Aretha Franklin appeared via satellite. Ex-judge Jennifer Lopez returned with Pitbull.
Keith Urban jumped onstage to accompany Kree on his country hit “Where The Blacktop Ends.”
Outgoing judge Randy Jackson, who departs Idol after 11 years on the panel, was given a tribute montage of some of his most memorable moments.
“I am so blessed and so honored and so lucky,” replied Randy. “Hopefully I touched their lives a little bit — they certainly touched mine.”
He also backed Mariah during a medley of her hits such as “Hero,” “My All” and “We Belong Together.”
But this season ranks as the lowest ever for the juggernaut, with doubts about any of the judges returning.
