Sources on the set of the film ‘Justin To Kelly: The Rise of Two American Idols’, say that the winner of the first ever American Idol, Kelly Clarkson has been repeatedly seen getting all hot and heavy with the runner-up, Justin Guarini.

“Justin and Kelly are crazy about each other. It appears to be a full blown romance” said a set insider.

“They’ve done very little to hide their affection. They’ve been acting lovey-dovey around each other and are becoming more and more inseparable.”
