Are Aaron and Miley doing a duet?

American Idol's Aaron Kelly is definitely this season's sweet, shy David Archuleta type, but when Miley mentored the finalists, he was not bashful about his love for the Hannah Montana star! "I may have just a little crush on Miley," he admitted. Miley praised Aaron's singing (and gave him a hug!) but admitted to Ryan Seacrest that her fave contestant was Siobhan Magnus.
