In 2003, Miley began auditioning for a show that would soon become "Hannah Montana." However, she originally tried out to play Hannah's best friend, Lilly. Casting agents, however, asked her to audition to play the lead, a pop star leading a double life who was then named Chloe Stewart. Although she was at first deemed too young and too small for the role, Miley later snagged the part after a year of auditions, and Chloe was renamed Miley. Billy Ray then auditioned to play her dad on the show. Naturally, he and Miley had great chemistry, and he landed the part of Robby Stewart.
