I've only seen her a few times (on tv, movies, whatever) and don't obsess about her, but I think they're real...I did a quick google and found this quote:
"I've always hated my ears. They're big, and one of them kind of points out. I could fly with these things if I wanted to. I thought about having surgery to pin them back, but then I thought, no way, these are my ears, and I'm going to keep them, even though I don't like them.
The same goes for the way I feel about my breasts. When I first got boobs, I had a really hard time. I wasn't like other girls who started with a training bra then went to an A cup, a B, then a C. I went straight to a C cup. I was only 12 when it happened. I went through a phase where I only wore baggy sweaters to hide them as much as possible. The worst part was that I wasn't allowed to play certain parts because they were so big. Only during the last two and a half years have I started to feel okay with them. I've finally accepted them as just a great accessory to every outfit, kind of like a necklace."
At least she keeps you wondering, unlike all the other hollywood $2 skanks...
