There is a common misconception that they were dating due to their on-screen chemistry on the Disney Channel show "Hannah Montana," where they played best friends Lily Truscott and Oliver Oken respectively.

While there were rumors and fan speculation about a real-life relationship between them, neither Emily Osment nor Mitchel Musso ever confirmed or denied dating.
