Lady Gaga recently underwent hip surgery to repair a labral tear, most likely caused by her intense dance schedule. It is that work ethic that helped her top this year’s Forbes list of the top earners under the age of 30.

Forbes estimates that Gaga made around $80 million in the period between June 2012 and June 2013. The estimate does not include taxes, management deductions, and other fees associated with the insanely wealthy. However, that figure remains impressive due to the fact that she was unable to finish her sold-out tour due to the aforementioned injury. Gaga was also number two on the Forbes Celebrity 100 list.

Gaga joins six other women in the list’s top ten including Taylor Swift in third place and Rihanna in fourth. Those two are thought to have made $55 and $43 million respectively.

The Y-Chromosome is also represented on the list, although rather sparsely. Teenage money machine Justin Bieber landed the number two slot with an estimated income of $58 million. The other two young men on the list were Actor Taylor Lautner and musician Calvin Harris, who is in his last year of eligibility at age 29.

The rest of the top ten is rounded out by Kristen Stewart of Twilight fame, Oscar winner Jennifer Lawrence, pop queen Katy Perry, and the talented Adele, whose earning were estimated at $30 million.

The running themes of the list are clearly music and acting. A whopping seven of the top ten are musicians while the remaining three are actors. So for those of you out there with aspirations of seeing your children on the Forbes list in the future, invest in either acting or piano lessons.
