Jordin Sparks is proof that a healthy lifestyle does a body good!

The gorgeous and svelte 22-year-old songstress is flaunting her sexy bikini bod on the cover of Shape magazine's August issue.

Sparks became a household name back in 2007 while competing on American Idol.

As for shedding 50 pounds, she tells the mag:

    “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.”

The newly-slim singer can be seen opposite the late Whitney Houston in the film Sparkle.
