Miley Cyrus

Cyrus earned just $15,000 per episode of 'Hannah Montana,' but her recording income and merchandise royalties earned her $18 million a year by 2007, when she was 14. As her dual-identity fame was cresting in 2008, she earned $25 million and a place in the Guinness Book of World Records as the highest-earning child star. Her income blew up to $48 million in 2009 (the year of 'Hannah Montana: The Movie') and $54 million in 2010 (including her salary for her starring role in the tearjerker 'The Last Song.') Now that her days as Hannah Montana are over, the 18-year-old still managed to earn $15 million this year, according to Forbes. That includes her fees for two upcoming movies, 'LOL' and 'So Undercover.' All told, she's worth $120 million.
