I absolutely adore her and most movies she's starring in.
A little rumour: She was actually a pretty chubby kid, loved chocolate and all. Then WWII came and she became malnourished. However when she was on a cruise to Rome in order to shoot Roman Holiday, she gained about 15 pounds putting her at a slim weight (I think 5'7'' and 118 lbs, if I'm not mistaken) due to all the free food on the boat. The director was pretty angered and didn't believe she could lose it because he had some weight issues too, but she did (in about two weeks) and then vowed to herself to never exceed 103 pounds.
And I just have to add some picture spam... :]
