Jordin Sparks Shapes Up with Reebok

Songstress Jordin Sparks has undergone an amazing transformation by dropping four dress sizes! The American Idol Season Six winner was recently spotted running errands in Reebok’sEasyTone Inspire sneakers and new line of shapewear in downtown Detroit where she’s filming Sparkle. She star's in the film, which is loosely based on the story of The Supremes, alongside Gossip Girl’sTika Sumpter and Whitney Houston. As soon as Jordin slipped on the shapewear, which has compression panels for a slimmer silhouette, she got an instant confidence boost that motivated her to get moving.

“I love to be active but to actually make exercise a priority in my life was new to me,” she explained. “So when I discovered Reebok Shapewear…a light bulb went off in my head. As soon as I put it on I immediately felt confident!”

Reebok Shapewear will be available November 25th on
