Miley Cyrus has a smile so big that it lights up her entire face. That’s why her dad, Billy Ray Cyrus, nicknamed her Smiley Miley. This young lady is not only a happy person with a bubbly personality, she is also a very talented actress and musician. Her big break came in 2006 when Disney Channel aired the first episode of Hannah Montana in which Miley had the starring role. She is now one of the most popular stars on the Disney roster. Fortunately, Miley hasn’t let stardom change her. She is still the sweet country girl from Tennessee with a smile that is just about as big as she is.
