I personally feel that she sold out to Hollywood, she wasn't getting any good film roles so she had to lose weight and YES she doesn't look right, her head is too big on her body now. She has NO CURVES, like she had before.
I always thought she was beautiful and more of role model because I thought, she loved the way she looked and didn't care what other people thought. I also had seen her in person and let me tell you, she was probablly a size 10, she was not as big as people thought she was. To me I would die to be a size 10 or 12 even. But that is overweight in the public eye.
If you aren't a size 2 or lower then you are fat and THAT is absolutely ridiculous.
