Adam Lambert Is a Diva

Who's the greatest diva of all? Maybe it's Adam Lambert, who confirms he will host, perform, and pay tribute to the late Whitney Houston and Donna Summer at the upcoming VH1 Divas concert.

"I'm so thrilled to be hosting VH1 Divas this year," Lambert says in a statement. "I have a feeling it's going to be the most fabulous concert of the year! And LIVE!! Get ready for some amazing performances, killer fashion, and fierce divas!"

The concert, which benefits VH1's Save the Music Foundation, will air live December 16 at 9 p.m. and will feature performances by Miley Cyrus, Demi Lovato, Ciara, Kelly Rowland, and Jordin Sparks.
