Forbs magazine has published a rating of singers with the highest incomes, the first line in it was taken by Lady Gaga.
According to estimates of the magazine, the singer earned in 2011 90 million dollars. This amount brought her the sale of albums and concerts.
Lady Gaga, of course, well done - a hard worker. Jumping around the stage in ridiculous outfits on huge heels is also a labor, therefore, according to the editorial staff Know All, the earnings are deserved.
