Jordin Sparks' bikini photo is making the rounds on the Internet. The singer showed off her new slim physique on Twitter on Sunday in a bikini self-portrait, writing, "I don't know why but my bathing suit reminds me of fruity pebbles."

The 21-year-old, who recently spoke with SheKnows about her dream come true of singing for the Disney movie African Cats, says that weight loss is something anyone can do. Jordin Sparks tells People, "It was just a shift in my thinking. Instead of talking about being more active, I just got up and did it."

"There's no secret," adds Jordin. "Anybody can do it." Rumor has it Jordin Sparks' weight loss is in the area of 30 pounds, with the star dropping from a size 12 down to a size 6.

As for the teeny bikini in the photo? You won't have to fork out big money to emulate Jordin's style. She shares, "Top is from Target and bottom's from Old Navy!"

Another star who has recently shown off her newly svelte figure in bikini photos is actress Sara Rue, who lost 50 pounds and is now a spokesperson for Jenny Craig.
