The series also stars Emily Osment as Lilly Truscott, Mitchel Musso as Oliver Oken, and Jason Earles as Miley's older brother Jackson Stewart. Moisés Arias appears as Rico Suave in a supporting role throughout the first season; he was promoted to the main cast for the show's second season. The network dropped Musso's character Oliver to a recurring role in the fourth season because he had been cast in "Pair of Kings", which was developed for the sister channel Disney XD.
