Jordin Sparks' jaw-dropping new bikini body is definitely something to sing about.

During a recent getaway to the Bahamas with boyfriend Jason Derulo, the singer/actress showed off her 50 pound weight loss — which she first debuted last summer — in a sexy, printed bandeau top and black bikini bottoms.

Earlier this summer, the Sparkle star, 22, opened up to Us Weekly about how she lost the weight — and how she's successfully kept it off.

"There is no secret," the Season Five American Idol champ explained "It's just better eating and working out! It's definitely a daily thing."

One of her favorite ways to stay fit is with high-energy dance classes like Zumba.

"My mom's best friend is a Zumba instructor and I loved it," she said. "I started with walking then went to jogging and then Zumba." In addition to her cardio-heavy classes, "I started [working with a trainer] and we did 30 minutes of circuit training," Sparks revealed. "So I didn't feel like I needed to be in the gym for two hours."

Sparks' hard work has paid off big time; this summer, the pop star donned a bright blue bikini on the cover of August's Shape magazine.

"I could only dream of having a cover and looking like that," she told Us. "I thought, 'I did it!' I had to walk back to my dressing room and . . . pull myself together because I was overwhelmed. I cried. I shed a little tear."
