In the accompanying interview Miss Klass, the new face of Marks & Spencer, describes how she and her fiance Graham Quinn - a former bodyguard from her Hear'Say days - are preparing for the arrival of their baby girl, who is due in August.

Striking a pregnant pose: Klass, Moore and Spears

"Last week I cleared a rail of my wardrobe and we went out and bought little pink outfits for the baby," she said. "I let Graham choose the first one because I thought it was an important bonding step - his daughter's first outfit."

Demi Moore caused outrage among religious groups when she first posed naked and heavily pregnant for the August 1991 cover of Vanity Fair.

The actress, then 29, was seven months pregnant with her second child, Scout LaRue, by then husband Bruce Willis. The cover, shot by Annie Leibovitz, proved so controversial that the magazine was packaged in a plain brown paper in stores across America's Midwest.

Famous mothers-to-be who have copied Miss Moore's pose include singers Britney Spears and Melanie Brown, models Cindy Crawford and Nell McAndrew and Italian actress Monica Bellucci.
