I think Heidi's a beautiful lass. Did she look better before she started getting facial surgery? Yes. I think she's still very much a looker though. Very striking when she's done up, I think. I hope she doesn't have any more alterations in the future though. She will end up ruining her looks if she carries on getting things done. The way she is now though, I think she's still in the "beautiful zone".
Edit: Okay, as far as being sexy goes, I suppose she could be if she dressed the right way.
