Madonna

There's a reason that this 50-something diva has always been cited as the undisputed queen of controversy—and that's because she is. No other personality in history has been quite so, well, voluntarily controversial as her and considering she's the only one on this list to have a 'top controversies' blog about her life, she'll always be a winner on this front.

If you don't know what exactly is controversial about Madonna, you might want to find something pointy and burst the bubble you're living in, but we'll humour you anyway. Think conical bras, sex on stage, songs about abortions, unseemly (and this is the most polite adjective we could think of) videos, best-selling books about sex and dates with men who could easily be her children, to name a few of the things Madonna has doled out to us over the decades.
