Listen To Whitney Houston and Jordin Sparks' 'Sparkle' Duet, 'Celebrate'

Op-Ed: Why 'Sparkle' Will Shine for Young Women

On Sunday night (May 20), Jordin Sparks honored her late "Sparkle" co-star, the legendary Whitney Houston, with a heart-wrenching performance of "I Will Always Love You" at the 2012 Billboard Music Awards. Less than 24 hours later, a more upbeat collaboration between Houston and Sparks for the "Sparkle" soundtrack, titled "Celebrate," was officially unveiled.

The track, which premiered on Ryan Seacrest's syndicated radio show on Monday, is a relentlessly optimistic jam that seamlessly interweaves Sparks' "American Idol"-winning vocals with those of her idol. "Though we've been going through changes/Just trying to make it from day to day/Tonight, don't you worry about a thing/Just cast your cares away," Houston sings in the second verse before the irresistible chorus returns.
