Returning to the show responsible for kick-starting her successful career, Kelly Clarkson was back and better than even on Thursday night's (April 14) episode of "American Idol".

The Fort Worth, Texas native joined forces with country singer Jason Aldean to perform their hit duet “Don’t You Wanna Stay.”

Clarkson and Aldean's song has mounted quite a successful sales effort thus far - as it reached the million downloads milestone last week.

Clearly excited to be back on "Idol" once again, Kelly called Casey Abrams "delicious" after her performance after previously making her contestant favorite known via Twitter, as she cutely wrote, "I might have a bit of a crush on Casey on American Idol this season. He's super cute and obviously super talented."
