Veteran screen siren Sophia Loren insists her long-lasting looks are 100 percent natural, because she refuses to resort to cosmetic surgery.

At 75, the Italian actress looks at least a decade younger - but she insists she's had no help preserving her looks.

Loren, currently starring in movie musical Nine, tells People magazine, "I don't believe in having work done, because then everybody looks the same."

But the Oscar winner admits she hasn't given up the quest for perfection, confessing, "I should exercise more. Lose a couple of kilos."
