Forbes Magazine just released their annual Celebrity 100 Power List, which features some familiar faces—and some surprising newcomers. Oprah Winfrey, who earned an estimated $315 million in the past year, topped the list.  Lady Gaga came in at No. 4, earning $62 million after not even making the list last year. Forbes.com cited that Gaga’s success and thus high placement is due to “a mixture of extreme theatricality, catchy hooks and an image that is edgy, yet business friendly.” She also beat out other top-performing pop contenders including Taylor Swift (who ranked at 12) and Madonna (who snagged 10th place). Another newbie? Twilight Saga star Robert Pattinson, who placed right in the middle at No. 50.  Other top performers included Beyonce Knowles and hubby Jay-Z (places 2 and 15, respectively), James Cameron (for his flick Avatar) and Tiger Woods.
