Jordin Sparks has been putting in some work at the gym.  The American Idol season six winner recently tweeted a photo of her in a bikini showing off a new, slimmer physique.

“I don’t know why but my bathing suit reminds me of fruity pebbles,” Sparks tweeted along with a photo of her in a two-piece bikini lookin all kinds of good.

Jordin is currently working on her third album, and recently released the video for “The World I Knew,” which is featured in the film African Cats.
