Brittany Murphy, 32 Years Old
The "Uptown Girls," "Clueless," and "Riding In Cars With Boys" actress was every scene's It Girl in the 90s. She dated Ashton Kutcher and Simon Monjack for a time and was never seen without her signature honey-blonde hair. Though the media suspected she had a drug addiction, she denied it. She died from pneumonia in 2009, though an overdose was ruled out as her cause of death.
