Page Six reported that both Nixon and Sex And The City co-star Kristin Davis underwent cosmetic surgery earlier this month.
The pair were said to have visited New York's Roosevelt Hospital on separate occasions, with Davis opting to have varicose veins removed from her legs.
A source said: "They both made sure they did it on the quietest day of the week."
Nixon's representative insisted that there is no truth to the claims. Davis's spokesperson has yet to comment.
