Nicole Kidman is not pregnant... but she may

Nicole Kidman is not pregnant, PEOPLE reports.

Kidman's expecting a baby was first reported by the U.K.'s Daily Mail, which said The Hours Oscar winner, 40, had told friends and family members over Christmas that she and her husband of 18 months, Keith Urban, were expecting their first child together.

"It is incorrect," the spokeswoman tells the paper. "She must have had about 30 babies by now."

Still, a friend of Kidman's tells the Herald Sun it is "conceivable" that the actress is nearly three months pregnant.

"She did have a small baby bump a month ago, so it would be reasonable that she'd now be three months and telling her friends and family," the unnamed friend is quoted as saying.
