She was born to be a megastar, apparently. With a staggering $90 million earned in 2011, Lady Gaga made more money than any female singer, by a mile.
Taylor Swift was second with half of that total ... a paltry $45 million.
Katy Perry was right behind Swift with $44 million, while Beyonce Knowles and Rihanna finished off the top five, earning $35 million and $29 million respectively.
Gaga's impressive earnings were mainly due to her tour, which grossed $1.3 million a night, as well the Born This Way singer's many endorsement deals.
The earnings estimates were compiled by Forbes with help from data from Pollstar, RIAA and others, as well as extensive interviews with industry insiders.
The totals encompass all aggregate pre-tax income earned from May 2010-May 2011, before expenses, i.e. subtracting agent and manager fees, and so on.
