Nicole Kidman has denied the News of the World report that she is pregnant, but she does admit to wanting to have a child wtih her husband, singer Keith Urban.

Rumours started when Kidman was seen outside St John's Health Clinic in Santa Monica - a facility that has been the birthplace of several celebrity babies. News of the World also reported that she was seen purchasing baby stuff at Petit Tresor including a $400 diaper bag.

The Oscar winner's publicist, Wendy Day, denied the paper's report saying that Nicole is absolutely not pregnant. "She's looking forward to giong outback and riding a horse and being here [in Australia] for seven months making a film. I hardly think she will be able to do that if she is pregnant," she said.

Nicole and Keith arrived in Sydney on Sunday and spent Easter with the family, including Kidman's new born niece. The arrival of her sister's fourth child is a good explanation for the shopping spree at Petit Tresor.

Nicole is scheduled to remain in Australia for up to eight months filming Baz Luhrmann's romantic adventure "Australia" with Hugh Jackman.
