Madonna makes the most of all performers

Give it up for Detroit's finest export:  Madonna is the top-earning celebrity of 2013 determined by Forbes magazine. 

The mother-producer-director-actor-philanthropist-singer 55, became a part of an elite group of people whose bank balances topped $1 billion. She earned approximately $125 million alone between June 2012 and June 2013.

How did she do it? The singer's "MDNA" world tour grossed more than $305 million last year. She also earned $75 million from concert merchandise and $10 million from TV rights and DVD sales.

Investments in her Hard Candy gym franchise and coconut drink Vito Coco, as well as a $10 million deal with Smirnoff vodka, increased her coffers too.

Madonna's "Truth or Dare" perfume has earned $60 million in sales, while her Material Girl clothing and accessories line is expected to draw another $10 million in 2013.

Celebrities these days must become a brand. Whether it's selling clothes and shoes (Selena Gomez and Jessica Simpson) or fragrances (Paris Hilton and Beyonce), many do anything to make an extra million.
