Although the New York Post reported that the "Sex and the City" star had cosmetic surgery at a Manhattan hospital "on the quietest day of the week," Nixon told the New York Daily News the story is "totally false" and she simply went to the hospital for a "three-monthly checkup."

"I was in the Oncology Department," she told the newspaper. "I guess they think that means 'plastic surgery ... We got a call from (the Post) asking if I'd had breast augmentation, and my publicist laughed at them and said, 'No, of course not.' But they printed it anyway. If I was going to get a boob job, wouldn't it make sense that I'd get it before 'Sex and the City'?"

"The story was totally false. It would be annoying and disheartening in any case, but particularly because I've been so open about my breast cancer," Nixon said.
