After months of speculation, VH1 has finally unveiled the official lineup for its Divas celebration. Early reports showed an all-star lineup for a Whitney Houston tribute. Alas, those rumors didn’t hold any weight. However, the roster presented will surely provide for an entertaining show.

Ciara, Kelly Rowland, Jordin Sparks, Miley Cyrus and Demi Lovato have been booked to perform. Tributes honoring late legends Whitney Houston and Donna Summer will be featured in the special. Adam Lambert will host the event, which broadcasts Sunday, December 16th.
