Best Celebrity Duet: Demi Lovato and Fifth Harmony
Go girl power! Simon Cowell proved how shrewd a businessman he is when he paired his group Fifth Harmony with frenemy Demi Lovato – with whom he had a love/hate relationship all season – on the former Disney star's own "Give Your Heart a Break" during finale week. It seemed like a smart move at the time, serving as both a cheeky peace offering and a last-minute grab for votes. Alas, his plot failed and Fifth Harmony landed in third place, beaten out by winner Tate Stevens and runner-up Carly Rose Sonenclar.
