Following her recent dramatic weight loss, Jordin Sparks was more than happy to show off her bikini-ready body on Twitter.

"I don't know why but my bathing suit reminds me of fruity pebbles," the 21-year-old American Idol winner wrote, linking to a picture of herself in a two-piece.

How much weight has Jordin Sparks lost? You be the judge

Sparks first showed off her new slimmer figure in late March, telling HollywoodLife.com that she lost 30 lbs. after she started working out with a personal trainer in 2009.

"Any time I find time — or I'm not sleeping — he's like, 'Let's work out, let's do something.' I'm like, 'no,' but he gets my butt up and I've got to do it," Sparks told the site. "It's fun to do that."

Sparks is expected to release the first single from her upcoming third studio album in the coming weeks.
