Miley Cyrus, Demi Lovato, Jordin Sparks and Ciara are set to perform tributes to music icons Whitney Houston and Donna Summer at the 2012 Vh1 Divas event.

Former Destiny's Child star Kelly Rowland will also be hitting the stage at the annual celebration, which will be hosted by former American Idol finalist Adam Lambert - and he can't wait to take charge of the bash.

The excited singer says, "I'm so thrilled to be hosting Vh1 Divas this year. 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!"

Vh1 Divas will be broadcast live from Los Angeles on 16 December (12).
