Meet the next Hillary Duff. Miley Cyrus plays undercover teen pop star Miley Stewart -- her friends don't know she's actually singing sensation Hannah Montana! -- on the Disney television series and film. Expect the same preternatural maturity and high-sheen production as Duff's upbeat pop-rock, this time with a dose of false humility: songs like "Just Like You" and "The Other Side Of Me" feign to probe the depths of fame and Montana's conflicts over her double life. Christian rockers Everlife and lite-rap act B5 make appearances.
