Former judge Simon Cowell once told Candice Glover she'd never amount to more than a lounge singer, but after three try outs and a grueling season, she was crowned the winner! The 23-year-old who is known for her powerful range beat out Southern gal, Kree Harrison. The shows big finale had plenty of other memorable moments including performances from Frankie Valli, Jessie J., Aretha Franklin, Jennifer Lopez, Mariah Carey and more! Then there was a somewhat funny and emotional tribute to judge Randy Jackson who just last week announced he was leaving the show after twelve seasons.

Jessie J has posted snippets of her new single, Domino, on Twitter.
