Who's the one person capable of knocking Oprah Winfrey out of Forbes' top spot on the list of the world's most powerful celebs? Angelina Jolie. Winfrey, who topped the list last year, was dethroned and moved to the No. 2 spot on the annual Forbes list, which came out yesterday. "Though viewership for the self-made billionaire's flagship chat fest, The Oprah Winfrey Show, continues to erode, her earning power remains resilient," the list said. The Celebrity 100 list ranks the rich and famous based on media exposure and earnings over the past year.
