Oh no, with +20lbs. she is quite womanly in form. Those dimples in her face really come out, and it gives her that round glow overall without being fat at all. Director Josh Weadon used to have his actresses gain 20lbs. just for the same effect.
And as far as her teeth, I think it gives her a little imperfection that makes her even more attractive when smiling, while they are not bad overall. "Hollywood veneer" is hardly my idea of perfection, let alone does not last. Her teeth are just fine.
Damn if she doesn't look stunning glam'd up like in her Boobpedia profile shot:
