Jordin Sparks shows off her fit bikini body on the August 2012 cover of Shape magazine.

The 22-year-old singer/actress opened up on her weight loss to the mag.

“I just wanted to be healthy,” Jordin shared. “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. 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.”

Jordin also dished on her Zumba fitness routine and starring alongside the late Whitney Houston in their upcoming movie, Sparkle.
