'Forbes' Magazine has released it's list of most rich and powerful, and Lady Gaga knocks out Oprah Winfrey for the number one spot.

Gaga making over 90 million last year and using social media networking sites to boost her popularity has  helped.  She hit a milestone last week by hitting 100 million followers on Twitter.

Winfrey, still ranking in at second, but has not mastered the art of the social media like Gaga has. Right behind Winfrey in third place is the lovable and adoring pop sensation Justin Bieber.
