The actress, however, says she got out of the wrinkle-smoothing injections because she likes to have control over her facial expressions, the Daily Mail reported.
"No surgery for me; I did try Botox, unfortunately, but I got out of it and now I can finally move my face again," she said.
Nicole Kidman credits sticking to a healthy eating plan and rigorous exercise regime for her good looks.
"I am completely natural. I wear sunscreen, I don't smoke and I take care of myself, and I am proud to say that. Anybody can do anything to themselves - I don't judge - but personally I believe in being physically fit. That's how I was raised. I can't go in the sun because I'm fair-skinned. It was a nightmare when I was younger but it has its benefits now."
