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.
But the Melbourne Herald Sun quotes Kidman's Australian publicist as denying the Mail's story.
"It is incorrect," the spokeswoman tells the paper. "She must have had about 30 babies by now."
As for Kidman, says the rep, "She's in Australia making a film" – director Baz Luhrmann's epic Australia, costarring Hugh Jackman – "and her family are in Australia. She's happily ensconced away somewhere having a few days break. It's the silly season. As far as we're concerned, it's another rumor out of London."
Friend: It Is 'Conceivable'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.
Kidman and former husband Tom Cruise adopted two children during their 1990-2001 marriage: Isabella, now 14, and Connor, 12.
