I may be mistaken, but I believe she has had some kind of augmentation since she started in the adult biz. I believe she had the girls redone at some point in the last few years, but that she has always had implants since we've seen her.
So basically, I don't think there are photos or vids of her with natural boobs, unless there are some from her personal life floating around.
On the other hand, I met her at a couple conventions and took photos with her both times. She stood in front of me and placed my hands on her boobs for the photo and I can tell you they're surprisingly soft.
