Kidman's attire fuels pregnancy rumours

Nicole Kidman has failed to quash rumours that she is expecting a baby.

A tabloid report which claimed that Kidman is pregnant has been officially denied by the actress's representatives.

However, there has been further speculation after Kidman was spotted wearing a maternity-style dress while out for lunch with her husband Keith Urban in Sydney this week.

Nicole already has two adopted children, Isabella, 14, and Conor, 12, with her ex-husband Tom Cruise.
