Everyone may be talking about her star-studded final shows, but Oprah Winfrey has been unseated as No. 1 on Forbes's 100 Most Powerful Celebrities by Lady Gaga. The singer, who was fourth last year, bumped Winfrey to second place. She earned $90 million on her tour and has 32 million Facebook fans and 10 million Twitter followers. Plus, Gaga’s first single off her sophomore album, Born This Way, was downloaded 1 million times in five days. Oprah earned $290 million last year, but she had taken a $25 million cut in earnings due to a reduced payday at Sirius XM Radio. Teen sensation Justin Bieber debuted on the list at No. 3. Some surprises include Bravo star Bethenny Frankel—who earned $55 million and sold her Skinnygirl Cocktails to Fortune Brands—and Tiger Woods, who cracked the top 10 by taking in $3 million an appearance overseas.
