But who could have guessed that it would be former American Idol judge Paula Abdul?\n\n\n\nPaula's reveal as one of the light-up dancers shocked her former colleague Simon Cowell. They appeared together in early seasons of American Idol. Paula also had a funny run-in with AGT judge Julianne Hough earlier this year at the BBMAs, when she hit her with a hat during her performance.\n\n\n\nPaula was previously a head choreographer for the Laker Girls, before starting her career in music in the late '80s. She'll have a Las Vegas residency called Forever Your Girl starting this October.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=JBfJlZ6HqJ0\nCher performs "Waterloo" on the "AGT" finale.\n\n\n\nCher Takes The 'AGT' Stage\n\n\n\nTalk about an iconic performance. Cher took the stage in a '70s-themed performance of ABBA's "Waterloo." She was accompanied by a giant disco ball and back-up dancers in retro outfits.\n\n\n\nCher is a legend in both the music and movie worlds. She started out performing with her then-husband Sonny Bono in the 1960s, and has since become a Grammy-winning solo artist. She's also appeared in movies like Silkwood and Moonstruck, for which she earned an Oscar.\n\n\n\nLast year, Cher released an album of ABBA covers called Dancing Queen. She's reportedly working on a follow-up album.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=g7yqx8p0zJI\nLeona Lewis and Kodi Lee perform a duet of "You Are the Reason" on "AGT."\n\n\n\nLeona Lewis Sings With 'AGT' Winner Kodi Lee\n\n\n\nOne of the most memorable performances of the night came from AGT winner Kodi Lee and singer Leona Lewis.

She won The X Factor in the UK in 2006, and went on to release such songs as "Bleeding Love" and "Footprints in the Sand." She also appeared in Cats on Broadway.\n\n\n\nIn 2018, Leona and Calum Scott released a duet of "You Are the Reason." Calum is also a talent show contestant, having competed on BGT.
