1. Miley Cyrus
The most successful and controversial Disney star to date. She was every little girl’s hero when she was Hannah Montana. After the show ended she came out with a cute album, got engaged to Liam Hemsworth and starred in few movies. But this past year, she dropped all that. There was no turning back after twerking at the VMAs. She publicly agrees with marijuana, she parties non-stop, and does whatever she pleases. Miley is definitely the naughtiest of them all.
