Jordin Sparks looks ravishing in a bikini, and she has every reason to be excited about flaunting dem curves in a two-piece.

The 'No Air' songstress has lost 50 pounds since her 'American Idol' days and it's all thanks to good old fashioned dieting (which for Jordin, just means eating healthy) and plenty of exercise.

She recently admitted to Women's Running Magazine that she exercises listening to BF Jason Derulo's music. It makes total sense! His music is way uptempo, and he's the one she's aiming to please in her bikini anyways, right?
