GASP! Sienna Miller has followed in the footsteps of Demi Moore and posed naked with her baby bump. Just weeks before she was about to pop out (deep breath) Marlowe Ottoline Layng Sturridge, her daughter with Tom Sturridge, the 30-year-old unveiled her pregnant body for artist Jonathon Yeo, all in the name of art. We're impressed to see Sienna went for the pregnant Oscar look: a mahoosive bump spray-painted gold (natch).
This 'pose when you're preggers' phenomenon started with that Demi Moore Vanity Fair cover waaay back in August 1991. Super famous photographer Annie Leibovitz shot Demi when she was seven months pregnant and dressed in nada but diamonds. The cover sent shockwaves through the fashion world (think One Direction posing with puppies times 100).
A new fash mag trend was born and from then on almost every pregnant celeb tried to copy the iconic Demi pose. Britney Spears's Harper's Bazaar cover was a good'un, as was Jessica Simpson's ELLE although we're not so convinced by Mariah Carey for *ahem* Life & Style. The supers also got on board with everyone from Cindy Crawford and Claudia Schiffer to Eva Herzigova posing naked. Well why wouldn't they?
Like Sienna Miller, Kate Moss and Jerry Hall went down the art route rather than gracing a magazine cover with Kate and Jerry starting the trend when they posed for artist Lucian Freud. His painting of preggers Moss is valued at a stonking £2,500,000 - £3,500,000. How much do you reckon Sienna Miller's naked preggers art will be worth? If you're desperate to see the portrait in the flesh (or place a bid), it's due to be exhibited in Under My Skin at the Circle Culture Gallery in Berlin. Book. Tickets. Now.
