The Queen Monster's $90 million in earnings and mastery of social media pushed her past perennial winner Oprah Winfrey. Not that Oprah's doing badly.
Lady Gaga topples Oprah Winfrey from her No.1 spot on Forbes List, which she's given up for only the third time in seven years. Gaga is there not just because of the $90 million she earned with a monster tour, but also because of her 32 million Facebook fans and 10 million Twitter followers–aka Little Monsters–who helped move 1 million digital downloads of her recent single "Born This Way" in only five days. They're also happy to buy the MAC makeup, Monster headphones and Virgin Mobile phones she features in her videos.
