Supermodel Heidi Klum has vowed never to go under the knife - because she wants to convince age-obsessed women that growing older is a natural part of life.

The German beauty and mother-of-three refuses to succumb to the mounting pressures of appearing ever-youthful now that she's in her mid-30s. And she insists she is proud of her developing age lines because they reflect life experiences.

She says, "There's something odd when you're 35 or 40 and ironed to the max. You change with time, and its fine. Everywhere there are these stand-up cards saying, `Have a little silicone while you get your roots done.' I want to be the opposite of that."
