     Forget Britney Spears, who is the new pop princess that makes thousands of American teenage girls

scream with excitement at her concerts and rush to the store to buy her latest CD?

    The answer is Miley Cyrus. After starring in popular TV shows and hit movies, the 16yearold released

her fifth album, The Time of Our Lives, on August 28.Its lead single, Party in the U. S.A., is wildly

popular.

     Cyrus has built her success largely on a role she has played. On TV and the silver screen, Miley Cyrus

is Miley Stewart.She is popular at school during the day and at night, she is a famous pop singer named

Hannah Montana.

     Her soaring popularity goes to her head. So Stewart's father takes her home from Los Angeles to

Tennessee, a southern US state, for a dose of reality(体验生活). The journey kicks_off an adventure

filled with fun, laughter and romance.

    While there, she has to cope with her city girl's unfamiliarity with country life and gradually learn what

family is all about.

    "Hannah Montana, at heart, is every Disney princess show you've ever seen," writes Michael

O'Sullivan, a reporter with the Washington Post."Only with a limo(房车)instead of a

pumpkinturnedcoach(南瓜马车), a microphone stand instead of a magic wand(魔法棒)and a prince

who wears a cowboy hat."

     But the journey of looking for one's inner self goes beyond the big screen. Actress Miley Cyrus has a

celebrity father, Billy Ray Cyrus, a famous country singer.The teenager doesn't want people to think she

has taken a shortcut to success."It's about how I find out who I am. I get to know that you need to be

me."
