Oprah Winfrey has returned to the top of Forbes magazine's list of the most powerful celebrities. It was the fifth time at the top for Winfrey, who had dropped down the list after she stepped away from her syndicated daytime TV show. (Last year the list was headed by Jennifer Lopez, who dropped to 12th this year.) Forbes measures power by wealth, mentions in the press, appearances on television, and discussions in social media. Winfrey, the magazine said, still wields an enormous amount of power, which is really what we look for in our fame matrix. She is taking this cable network and turning it around just through the sheer force of her will, her connections and her ability. Runners up were: 2. Lady Gaga, 3. Stephen Spielberg, 4. BeyoncÃ©, and 5. Madonna. Nineteen-year-old singer Justin Beaver managed to make the list for the first time, coming in at No. 9.
