Gaga tops Oprah on power list

Flamboyant pop singer Lady Gaga ousted media mogul Oprah Winfrey to top this year’s Forbes celebrity power list released yesterday.

Gaga, whose real name is Stefani Germanotta, moved up four positions from last year to claim the top spot in Forbes’ annual “The Celebrity 100” 2011 list that measures power by entertainment-related earnings, media visibility and social media popularity.

Forbes rated the American singer-songwriter No. 1, estimating her earnings in the past 12 months as $90 million, but also noting her 32 million Facebook fans and 10 million Twitter followers.

“Lady Gaga beat Oprah this year because of her social media power,” Forbes editor Dorothy Pomerantz said.
