The term "music mogul" usually conjures up someone like Jay-Z, but it turns out his wife, Beyonce, has got everyone beat. Beyonce tops Forbes magazine's new list of Hollywood's top-earning "entertainment moguls in the making" -- a roundup of celebrities at or under the age of 35 who make money from multiple revenue streams. Beyonce took in a $87 million between June of 2009 and June of 2010, thanks to her income from touring and recording, plus her TV specials, movies, fashion line, fragrance and her endorsement deals with the likes of L'Oreal and Nintendo. Number two on the list was Britney Spears, who made $64 million in a similar period thanks to a concert tour, her line of best-selling perfumes and her endorsement deal and clothing line for Candie's. Lady Gaga came in third, raking in $62 million thanks to her sold-out Monster Ball tour, her record sales, her deals with Polaroid, Virgin Mobile and Monster Cable, and all those product placements in her videos. Fourth on the list was Miley Cyrus, who brought in $48 million through her touring, movie roles and merchandise. Taylor Swift was number five, thanks to her endorsement deals with Cover Girl and Sony, as well as her record-breaking album sales.
