Reps for slimmed-down American Idol star Jordin Sparks and “It Girl” hitmaker Jason Derulo have confirmed that the pop stars have been quietly dating since headlining a show in the Bahamas together last month.

The news comes as Jason releases his sophomore album, Future History, on Tuesday.

On Sunday, American Idol Season 6 winner Jordin Sparks showed off her slimmed-down figure by Tweeting a photo of herself posing in a bikini. The image quickly went viral. But Word on the Curb has it that the 21-year-old “No Air” singer has been sharing more than saucy snaps with Miami Heat hoopster LeBron James.

Say it ain’t so, King James!

The Snitch Circuit is abuzz with whispers that the NBA superstar, who’s expecting his third child with high school sweetheart Sabrina Brinson, has been secretly bedding the squeaky-clean Ms. Sparks for months.

Well, he did say he was bringing his “A-Game” to South Beach this season…Tiger Woods 2.0 anyone?
