The artists join previously announced performers Ciara, Miley Cyrus, Demi Lovato, Kelly Rowland and Jordin Sparks as they all pay homage to the most iconic divas of dance music, including the late Whitney Houston and Donna Summer. The celebration, hosted by American Idol diva Adam Lambert, will broadcast live from L.A.’s Shrine Auditorium on Sunday, Dec. 16, at 9 p.m. ET/PT.

Havana Brown, whose “We Run the Night” featuring Pitbull reached No. 26 on Billboard’s Hot 100 earlier this year, will serve as the event’s house DJ.

In addition to performing, former Idol champ and Foundation Ambassador Sparks also will host the official afterparty with special guest DJs The Dolls: Mia Moretti and Caitlin Moe, and KISSette.
