Happy Birthday to the one and only Madonna. In celebration of her birthday, and in anticipation of her upcoming movie, W.E., IA is going to take a look at her contribution to pop culture and fashion. Admittedly, each twist and turn in her career has generated nearly as many detractors as fans. And each decade has presented her with the challenge of staying relevant. But it can't be denied that nobody else has met these challenges the way she has. Why not take a look at how she's done it? We ♥ Madonna!
