1. Madonna: Since Madonna first (and most famously) mimicked Monroe in her 1985 hit music video "Material Girl," it seems like most of the starlets these days are just copying Madonna's imitation of Marilyn (did your head just explode?). The video featured a reenactment of Marilyn's iconic performance of "Diamonds Are a Girl's Best Friend" from the 1953 film "Gentlemen Prefer Blondes." Legions of wannabes soon began aping the singer who was parodying the actress, and well, the rest is pop culture history.
While Madonna claimed she never wanted to be compared to Monroe, she went on to dress up as the actress at the 1991 Oscars and pose in a multitude of Marilyn-themed magazine photo shoots since then, thus making her the ultimate wannabe. Nice try, Madge.
