Happy Birthday Madonna! Here's 55 Pictures That Prove The Queen Of Pop Is Growing Old Disgracefully! (PHOTOS)

Just because Madonna is celebrating her 55th birthday doesn't mean the Queen of Pop is about to start acting her age, hell no.

In fact, we'd argue that Madge is getting more outrageous the older she gets. Don't believe us? Well just take a look at our collection of photos from the last few years below and tell us otherwise!

The outfits are getting more revealing (if that's possible), the stage shows more provocative (ditto) and she's not about to start covering up just because she's edging towards 60 - quite the opposite in fact.

So as Madonna clocks in for another year on planet pop, we celebrate her 55th birthday with her 55 most outrageous photographic moments in recent memory.

We can't WAIT to see what she does to celebrate her 60th!
