NICOLE Kidman has finally confirmed the worst-kept secret in Hollywood - she has used Botox. The porcelain-skinned actor, 43, confessed to a German magazine interviewer she had used the face-freezing drug in the past but insisted she had now given it up. But age-defying Kidman said she stopped getting the injections because she couldnt move her features. I didnt like how my face looked afterwards, she said. Now I dont use it any more. The admission flies in the face of Kidmans previous claims she was completely natural and had never used the drug. Kidman had long been suspected as a devotee of Botox, along with ageless Hollywood stars such as Demi Moore, Jane Fonda, Madonna and Kylie Minogue. Herald Sun
