Rachel Green
Selena Gomez portrays the central character of Alex Russo. Gomez had left traditional school after the seventh grade and moved to Los Angeles. She sings the series' theme song, "Everything Is Not What It Seems". Her affiliation with the network led to the formation of the band Selena Gomez &amp; the Scene who Disney signed to their label, Hollywood Records, and subsequently, a prominent solo music career. Alex has been described as dark, crass and a jerk, as well as a "wisecracking underachiever". She is characterized by her rebellious and lazy attitude. Gomez asked for her character to remain "edgy" and tomboyish, to resemble her own style. Jennifer Aniston's portrayal of Rachel Green on "Friends" inspired her and she adopted similar mannerisms while playing Alex.
