The Born This Way singer hauled in the dollars despite having to cut short a lucrative concert tour after undergoing hip surgery.
She spent weeks in a wheelchair - a gold plated Louis Vuitton one of course.
Musical talent dominated this year's list.
Ranking an admirable second place was teen idol Justin Bieber, 19.
Despite more bad publicity than good over the last 12 months, Bieber isn't quite on the breadline with an annual income of $58 million.
Those teenage girls clearly have some spare money to spend.
And taking third place is the young country music star Taylor Swift. She clearly has more luck with her finances than with her string of disastrous boyfriends.
The 23 year-old You Belong With Me singer, who has dated 1D's Harry Styles amongst others this year, pocketed a cool $55 million.
Her earnings received a boost thanks to her album Red which sold 1.2 million copies in the first week.
Meanwhile Scottish singer songwriter Calvin Harris, 29, has made a fortune after morphing into a global DJ sensation.
He beat 25 year-old Rihanna into fourth place with earnings of $46 million.
Not bad for a boy who was discovered on MySpace.
Barbadian beauty Ri-Ri came in close behind with $43 million.
Songbird Katy Perry took sixth place.
Californian girl Katy, 28, who last month told Vogue how ex husband Russell Brand asked for a divorce by text message, is still a big earner making $39 million.
This whopping paycheck came despite a relatively quiet year.
The first of the non-musicians to make the list is the gorgeous Jennifer Lawrence who became Hollywood's darling this year with her Best Actress Oscar winning performance in Silver Linings Playbook.
Her earnings reached $26 million and things are only going to get better for the 22 year-old who can now command millions per movie.
And Londoner Adele, who won an Oscar this year for Best Original Song for Skyfall matched her age with her income this year. The 25 year-old earned $25 million.
Just behind Jennifer is Kristen Stewart, 23, with $22 million.
While her love life may have gone down the pan this year thanks to a highly publicized affair with married director Rupert Sanders and subsequent break up with Twilight co-star Robert Pattinson, her income remains unaffected.
And finally, Taylor Lautner may look like he has just stepped out of high school but he is yet another Twilight millionaire. The 21 year-old grabs the tenth spot matching Kristen's income with $22 million.
