PRO: As Britney, LiLo and the rest of their tragic sisterhood recede into infamy and late-night punchlines, Cyrus is cross-platforming her small-screen alter ego, pop star Hannah Montana: a concert movie proved one of last year's surprise box-office hits, and a full film is in the offing. Meantime, Miley has dedicated goofy YouTube vids to Jesus.
CON: How long before the big, bad world runs roughshod over that squeaky clean image? Clearly the media which gleefully latched onto a (false) pregnancy rumor last fall is dying to see it tarnished.
