Madonna will be the main performer at this year's Super Bowl half time show, and Nicki Minaj and MIA are set to join her. It will be nearly impossible for this not to end in controversy. Throughout Madonna entire career she has cultivated controversy. MIA is known to release videos like this one: http://vimeo.com/11622786 and in general has some pretty revolutionary if not always completely thought out political attitudes. Nicki Minaj's ass in front of 300 Million people watching the game might be a controversy it self; but I am sure their will be an aspect of her rhymes in Madonna's song that are considered too sexual or something like that.
