Yeo displayed the revealing painting of the 30-year-old Factory Girl actress on his website, which is set to be shown at his '(I've Got You) Under My Skin' exhibition in Berlin.
The painting is reminiscent of the naked photograph of Demi Moore pregnant on the cover of Vanity Fair taken by Annie Leibovitz back in 1991.
Sienna and Demi aren't the only stars to go naked and pregnant, however. We take a look back at more, including Britney Spears, Cindy Crawford, Mariah Carey... and Chanelle Hayes.
