Los Angeles, Jan 29 (IANS): Actress Nicole Kidman has tried wrinkle-smoothing injections to look young, but now she wants to have flexible facial expressions.

"No surgery for me. I did try botox, unfortunately, but I got out of it and now I can finally move my face again," femalefirst.co.uk quoted Kidman as saying.

Otherwise, Kidman sticks to a healthy eating plan and rigorous exercise regime to look good.

"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," she said.

She will soon be seen in Park Chan-wook's psychological horror "Stoker", in which she portrays Evelyn Stoker, a mother, who is jealous of her daughter India Stoker, played by Mia Wasikowska.

The 42-year-old, who has two children - Isabella, 20, and Connor, 17 - with her ex-husband Tom Cruise, admits it was tough to play the character because her love for her kids is so strong.

"I was a huge fan of Park Chan-wook. I wanted to work with him and with Mia, who is Australian like me. It was an incredible experience. I play the part of a mother who hates her daughter. It couldn't be further from how I am. Nothing matters to me more than my children," she said.
