*After “American Idol” winner Jennifer Hudson dropped the weight, her actions may have started a trend. Another “AI” alum, Jordin Sparks, lost quite a bit and showed off her new bod in a bikini in Twitter photo (above). She shed a healthy 30 pounds.

She shared in a radio interview (“On Air with Ryan Secrest”) that she needed to make her health a priority.

“Instead of just talking about being active, I made it a priority,” she said. “It was one of those things where I was turning 21 and New Year’s was coming and it was like I’m not going to start my resolution on New Years day, I’m going to try to start it early and just stick to it,” she added.

She also mentioned she began losing weight after her break up with her ex (Steph Jones?).
