Everybody's been talking about Jordin Sparks' recent weight loss, and why not? After losing 30 pounds, Sparks says she's never felt sexier. It was catching pneumonia in December that prompted Sparks to start living healthier which led to her weight loss.

"I started slowly by walking the path around my house, and then eventually walking a little bit faster, and then actually going and climbing up the mountain [near my home]," she said. "So it was literally a mountain to climb, but I did that."

In addition to hiking, Sparks began working with a personal trainer, taking Zumba classes with her mom and making small changes in her diet. Her hard work paid off when she posted a photo of herself in a two-tone bikini on Twitter saying, "I don't know why, but my bathing suit reminds me of fruity pebbles."

"For me to even be talking about bikini confidence is crazy," says the now slender singer. "If you had asked me a couple of months ago, I probably would have been like, ‘what are you talking about…' so it's actually huge for me to even feel okay with putting a bikini on." We think Sparks looks more than okay in her bikini!
