Liv Tyler has vowed never to have plastic surgery - because it makes people look "creepy."

The stunning actress says she takes care of her skin because she's determined she'll never go under the knife to preserve her looks. She revealed: "I don't want to ever have cosmetic surgery, so I want to do the best I can with what I have. I hate that look where people's faces have just changed. It's so creepy."

Liv, the daughter of Aerosmith rocker Steve Tyler, also revealed she's not the soft soul people see her as - and is actually a "tough cookie".

The brunette beauty, whose mother is famous rock groupie Bebe Buell, says she developed a thick skin to cope with ups and downs in her turbulent childhood.

She told Britain's Grazia magazine "I've never been fragile. I had these really hard things to deal with, and I did. I'm one tough cookie. "I guess I could have gone off the rails but, as a child, I watched my mother suffering so much for what she went through with men and all those other things. I decided then I didn't want to go through that."
