Forbes magazine issued its list of the year’s top-earning musicians … their year being June to June, that is. And it should come as no surprise that Madonna tops the cash heap.

What is (mildly) unexpected is just how much wealthier Madge has become. As Forbes reports, the Material Mom has garnered roughly $40-$50 million annually since 2002. Last year, however, she more than doubled that tally, rising to $110 million.

Céline Dion almost beat her, however. The chest-beating French-Canadian songbird raked in a cool $100 mil herself last year.Beyoncé landed in third, with $87 million.

The list was compiled by assessing earnings from album sales, touring, publishing and endorsement deals, with Billboard, Pollstar and Nielsen SoundScancited as sources.
