Tamar Braxton dances to new single King' on 'Dancing With The Stars'...

A lot of pop and R&B singers have done 'Dancing With The Stars.' Everyone from Mya, Brandy and Christina Milian to Nicole Scherzinger and Toni Braxton. 
But none have ever used it to promote their new music on the show. Tamar Braxton did however. Although she didn't actually sing new single 'King,' she and her show partner Val danced the Rumba to it, and it was quite sublime.

Perhaps she saw her poor first week sales projections for ‘Calling All Lovers’ and decided to fit in some last minute promo for the album.
