Oprah Winfrey, Beyonce Knowles, and Britney Spears are the top three highest earning women in entertainment, according to Forbes's annual list. Oprah sits squarely at the top with an estimated $312 million haul while Beyonce apparently pulled in about $82 million thanks in part to all her endorsement deals and hugely successful new fragrance launch. Britney Spears didn't even put out any new music this year, but she still raked in about $64 million with her popular tour, perfumes, and more. Rounding out the top five are Lady Gaga and Madonna. Beyonce, Britney, and Oprah have all been in the industry for a long time, but tell us — are you surprised that they are the top three earning women in entertainment?
