That's right! Lady Gaga has claimed the top spot for herself.

Gaga is there not just because of the $90million she earned with a monster tour, but also because of her 32million Facebook fans and 10million Twitter followers.

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

"She's the best example of how celebrities will need to manage their careers in the coming years."
