Hollywood actress Nicole Kidman has laughed off reports she is to follow in the footsteps of Demi Moore and Britney Spears by posing naked and pregnant for a magazine shoot.

The Australian star is expecting her first child with husband Keith Urban and was rumored to have striped off for a provocative photo spread with legendary photographer Patrick Demarchelier.

But Kidman admits that although she did take part in a shoot with Demarchelier, she did not bare all, and finds the idea of her posing naked while pregnant "hilarious."

She says, "'It's total nonsense. It was not that kind of a shoot.

"It's madness to think I did that or was even asked to do that. I'm just looking forward to having and caring for our baby."

Both Moore and Spears posed for controversial shoots for fashion magazines while they were pregnant, with Moore star gracing the cover of Vanity Fair in 1991 and the singer following suit in Harper's Bazaar in 2006.
