Adam Lambert hosted the two-hour TV event, which featured performances by Kelly Clarkson, Miley Cyrus, Kelly Rowland, Keri Hilson, Demi Lovato and Pitbull, among others, along with tributes to the late Whitney Houston and Donna Summer.
Kelly Rowland, Keri Hilson and host Adam Lambert perform “Last Dance” during the Donna Summer tribute. The mash-up was especially exciting for Rowland, who called Lambert “one of my favorites.”
Ciara set the stage on fire during her dance tribute to Michael Jackson, followed by a performance of “Got Me Good,” the second single from her upcoming album, One Woman Army.
Kelly Clarkson debuted her new engagement ring as she performed her latest single, “Catch My Breath,” to an ecstatic crowd of diva devotees. The original American Idol’s performance was one of the night’s most-anticipated and she did not disappoint.
Jordin Sparks saluted her Sparkle costar Whitney Houston with “I’m Every Woman” following a touching tribute from Brandy.
Kelly Rowland struts across the stage for her Donna Summer salute, during which she sang two of the disco queen's biggest hits, "I Feel Love" and "Bad Girls."
Ironically, rapper Pitbull brought the party to a close with "Don’t Stop The Party." While he may not be a diva himself, he certainly fit the bill when it came to the night’s dance-heavy theme.
X Factor judge and diva-in-the-making Demi Lovato delighted the Shrine Auditorium audience with her latest single “Give Your Heart a Break.”
Keri Hilson channeled her inner disco queen by donning a sexy look for Donna Summers’ “She Works Hard For The Money.”
A diva in her own right, Grammy-nominated jazz singer Ledisi showed off her powerful pipes when she kicked off Whitney Houston’s "How Will I Know." She was later joined by American Idol season six winner Jordin Sparks and newcomer Melanie Fiona.
Iggy Azalea and Natasha Beddingfield
Iggy Azalea and Natasha Bedingfield paid tribute to Deee-Lite with their own rendition of “Groove Is In The Heart,” during which they were joined by the legendary Bootsy Collins.
Proving her edgy haircut wasn’t just for show, Miley Cyrus turned up the heat and wowed the crowd with her punked-out performance of Billy Idol’s “ Rebel Yell.” Who knew spikes and leather would be in Hannah Montana's future?
Adam Lambert stole the show with a red-hot rendition of Donna Summer's "Love To Love You Baby" and "Hot Stuff." The tireless host later performed Madonna’s "Ray of Light," telling THR he found the vocally-challenging song a little intimidating, but ultimately, "had a lot of fun."
