Jordin Sparks Shows Off Rockin' Bikini Bod

"American Idol" season six winner Jordin Sparks is ready for bikini season and she tweeted a pic to prove it.

In the pic, Sparks shows off her curves in a polka dot bikini with an orange top and blue bottoms, writing, "I don't know why but my bathing suit reminds me of fruity pebbles. :)"

The 21-year-old singer looks noticeably thinner in the photo, and has reportedly recently dropped the pounds with exercise.
