Hollywood is losing young stars left and right. From Heath Ledger to DJ AM, it seems like every time you turn on your TV or computer, you are hearing about another star passing away. Brittany Murphy was in great movies like 'Clueless' and '8 Mile', but what is so sad about her passing is that we will never know what she would've accomplished down the road. I'm sure she had plenty of opportunities to add to her resume. I'm sure we will find out what caused her cardiac arrest, but until then, lets just wish her family our deepest condolences. I'm sure this Christmas will be most tragic and heartbreaking for them! Click on the pictures below for a link to Entertainment Weekly's photo montage of Brittany's most important roles.
