Lindsay Lohan's sister Ali denies plastic surgery

Lindsay Lohan's sister Ali denies that she went cosmetic surgery before. Recently she has just signed up with Next Model Management.

She explained about the rumor, "Because, like, when would I do that (surgery)? I'm 17 years old. That's not legal! I would need my mother's signature, and do you think my mom would sign off on that? No! It's not the right thing to do."
