Jordin Sparks is bikini sexy on the cover of Shape Magazine’s August 2012 issue!

Here is what the 22-year-old entertainer had to share with the mag:

On deciding to change her habits: “I just wanted to be healthy. I remember thinking, ‘I’m in my prime. I should be happy and fit.’ That was the moment I decided that changes needed to be made.”

On her old self: “I knew I had a long road ahead of me. I was barely working out, and my diet was a mess. I had to address when, what, and how much I was eating.”

On losing fifty pounds: “The weight really started falling off, and I could see my muscles. It was awesome.”
