Selena Gomez

Gomez made just $65,000 for last year's movie 'Ramona and Beezus.' Still, she's one of the highest paid child stars on TV, earning $30,000 per episode for Disney's 'Wizards of Waverly Place.' Between her TV work, her recording career, her clothing line, and her film work, she's worth about $4 million. She starred in the romantic comedy 'Monte Carlo' this year, whose failure suggests she has a way to go before she's as bankable in movies as in other media. Still, with Justin Bieber for a boyfriend, the 19-year-old is not going to be keeping a low profile.
