We'll give you a minute to try and guess who made more money between June 2012 and June 2013 over such artists as Lady Gaga, Justin Bieber and Coldplay.
Beyoncé? Close. Taylor Swift? Getting warmer.
Give up? We thought so.
The No. 1 spot goes to none other than....Madonna!
According to Forbes, the Material Girl earned a whopping $125 million during the aforementioned time frame, thanks largely to her hugely successful MDNA Tour.
Gaga came in second with $80 million, while Bon Jovi ($79 million), Toby Keith ($65 million), Coldplay ($64 million), Justin Bieber ($58 million), Taylor Swift ($55 million), Elton John ($54 million) and Beyoncé and Kenny Chesney (tied with $53 million) rounded out the top 10.
"With touring being the biggest revenue stream, if there's an opportunity for an artist to go out, if there's an opportunity for a promoter to curate a festival, people are doing it," Kevin Liles, who manages Big Sean, Trey Songz and Young Jeezy, told Forbes.
Other stars who earned big include Jennifer Lopez, Rihanna, Jay Z, One Direction, Katy Perry and Pink.
