The model doesn't understand why people would have unnecessary medical procedures, but admits she would never totally rule out going under the knife.
She said: "When I think about giving birth, I can't understand why women would opt for surgery, a Caesarean, if medically it's not necessary.
"I like to do things the healthy and natural way. Cosmetic surgery is one of those things where I find myself going, 'Oh no', where maybe in five years I might think, 'Well, you know.' So I don't know, but for the minute the idea turns my stomach."
Penny - who gave birth to rocker husband Rod Stewart's baby, Alistair, in 2005 - says she would consider surgery only to get her body back to how it used to be.
The 37-year-old star added to New! magazine: "I don't like the idea of changing myself and turning into something different but I'd think about it if it was a case of putting something back the way it was."
