Miley Cyrus - 2007
Like Ricky Nelson fifty years earlier, Miley Cyrus made her name playing a fictionalized version of herself on television. Like Ricky Nelson, her actual father acted alongside her in a television show that introduced her to America. The similarities between The Adventures of Ozzie and Harriet and Hannah Montana pretty much stop there, but both shows lead to huge hit singles and they created teen idols. Miley's rise was meteoric. Tickets to her 2007 Best of Both Worlds tour sold out faster than any tour in memory, and her show had monster ratings. It seemed like she was poised to become a more stable version of Britney Spears - especially after singles "The Climb" and "Party In The USA" crossed over to the adult market, but then things started falling apart. Her 2010 LP Can't Be Tamed failed to produce a hit, and Cyrus seemed over-eager to present a more adult image. Parents were horrified by Miley 2.0, and at the age of nineteen she already seems like a has-been. There's plenty of time for a comeback though.
