Lady Gaga Is Forbes' Top-Earning Woman In Music

Apparently, Lady Gaga made a little bit of money this year: She tops Forbes' list of Top-Earning Women in Music in 2011.

Just how much did Gaga make this past year? According to the magazine, the singer netted $90 million thanks to sales of Born This Way, her massive Monster Ball Tour and a number of endorsement deals.

But she's not the only lady making bank this year. Coming in at #2 is Taylor Swift. The country/pop superstar managed to make $45 million over the past 12 months with the never-ending success of her Speak Now album (which she released back in 2010) and her tour of the same name.

Nipping at her heels is Katy Perry. The Billboard record-holder amassed $44 million with continued singles from 2010's Teenage Dream and her California Dreams Tour.

Perhaps the biggest surprise in the top five is Celine Dion. The Canadian singer comes in at #4 with $19 million in earnings. The singer's success is due in part to her Las Vegas stage show. Adele squeaked into the top five at #5 with $18 million, earned mostly from the album sales from her chart-dominating 21. Alicia Keys also makes the list; Forbes reports that the singer earned $10 million, beating out her hubby Swizz Beatz for the year by $3.5 million.

Forbes compiled the list using income earned from May 2010 through May 2011. It also used data from Pollstar and RIAA, as well as interviews with industry insiders and the musicians themselves.

Many of the ladies on this list also landed on MTV's Songs of the Year countdown; Gaga's "Born This Way" comes in at #5 and Perry's "Firework" sits at #10.
