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.

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

family is all about.

who wears a cowboy hat."

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