Oprah Winfrey forbes hollywood celebrities

Oprah Winfrey has topped the Forbes magazine list of most-influential celebrities of 2013 for the second year in a row.

Forty-eight percent of people rated Winfrey, 59, as "influential," according to the magazine's survey this year.

The survey ranks 7,500 celebrities by 46 different attributes.

Despite her Oprah Winfrey Network (OWN) having struggled in the ratings since its launch, Oprah was down just one point from 2012.

Reuters pointed out that OWN had received a boost from Winfrey's January interview with cyclist Lance Armstrong, a world exclusive in which he admitted to years of doping.

She also conducted a high-rating interview with Beyonce.

Winfrey edged out Steven Spielberg, in second place, by just one point.

Fellow filmmakers Martin Scorsese, Ron Howard and "Star Wars" creator George Lucas round out the top five.

U2 rocker Bono and actor-director Clint Eastwood are also in the top-10.

Meanwhile, two of Oprah's proteges also made the top 10: Dr. Mehmet Oz, at seven with 40 percent of respondents rating him influential; and Suze Orman at number nine.

Commenting on her "notable attribute" — being "classy" — Forbes also listed Barbara Walters at number eight with a 37 percent influential rating.
