Forbes recently published its list of the Top 100 Celebrities in the world -- an eclectic who's who of some of the most powerful and influential people in entertainment industries across the world.

It was, perhaps, little surprise that American singer and entertainer Lady Gaga topped the list. The Born This Way singer's estimated earnings in the past 12 months stood at $90 million. Of course, apart from the money, her 32 million Facebook fans and 10 million Twitter followers could have had some role to play, in deciding her final position. 

Lady Gaga is followed by the former queen of American talk shows, Oprah Winfrey, with an estimated $290 million in earnings.

Canadian pop star Justin Bieber, 17, is third on the list and also the youngest celebrity there. He earned $53 million from sales of his albums, tickets to his concerts, and rights from his documentary, Never Say Never.
