Hollywood actress Nicole Kidman has rubbished media reports she is pregnant with husband Keith Urban's child. The Australian star, who has two adopted kids with former spouse Tom Cruise, ISABELLA, 13, and CONOR, 11, insists she has no idea how speculation about her expecting began. She says, "No, I am not pregnant. "One minute I'm being told I'm too thin, the next I'm told I'm fat and it must be because I'm expecting a baby. It's very confusing. "My mum rang me up and said, 'Are you pregnant?' And I said, 'No, Mum, you'd be the first to know.' And we just laughed about it because there's not much else you can do."
