I prefer the before picture. Slightly chubbier and cuter face. Still, she is a naturally pretty girl either way.
I feel a little bad for her. I know she put herself in the public eye, but she is young and naive and being manipulated by those around her who can profit. The haters start screaming "YOU HAD SURGERY!!!!" and pester her about it and she finally concedes "Yes, I did have surgery on my jaw" and then people bitch about how she should shut the fuck up. Just leave her alone and I'm pretty sure she will go about her business.
In the meantime, I would really like to see her in Playboy....mmm...
