The fashion world is reeling today over the tragic death of British designer Alexander McQueen, fashion's l'enfant terrible, who came up under the tutelage of his friend and idol, Isabella Blow, and was responsible for some of the most avant-garde fashions sent down the runway and red carpets on Kate Moss (whose hologram eerily hovered over his the runway of his Fall/Winter 2006 show), Sarah Jessica Parker, Gwyneth Paltrow, and, most recently Lady Gaga.

We thought we'd pay tribute to Alexander McQueen's untimely demise by showcasing our favorite McQueen looks on one of his biggest fans -- Lady Gaga, whose "Bad Romance" single debuted during the end of Alexander McQueen's Spring/Summer 2010 show in Paris. Obviously the love and adoration was mutual between these two icons.
