Miley Cyrus

11 Miley Cyrus
As Cyrus' name transcended the tween crowd, rumors began to circulate about the squeaky-clean teen. In September 2007, Internet gossip forced the 14-year-old star to publicly deny reports that she was pregnant. In an interview with Extra!, the teen starlet cited her vow to stay celibate until marriage.




Cyrus kicked off a 54-city arena tour last fall -- tickets sold out in record times. The tour was then extended to include 15 more dates.



Cyrus dyed her locks dark brown and unveiled an edgier image at the the 2008 Grammy Awards.




Cyrus looked far more sophisticated than her 15 years in a red Valentino gown at the 2008 Oscars. The "Hannah Montana" star jumped from the small to the big screen in 2008 with a 3D concert movie.




In a statement Sunday, Cyrus said, " I appreciate all the support of my fans, and hope they understand that along the way I am going to make mistakes and I am not perfect." While it's clear that Cyrus will continue to grow up in the limelight, perhaps it's faster than her tween following.
