Of course she's not. If she's done anything, Madonna's only satirised Marylin (Material Girl, Sooner or Later at the Oscars). "The only thing we have in common is our hair".
By now Madonna has been overtaken almost everywhere by Lady Gaga, except in Russia, Brazil and Italy, where the Queen of Pop is still part of the top of the coolest people. Even a Super Bowl performance couldnt change the tide.
