Nicole and Keith Won't Reveal Baby’s Gender

5/27/2008 Lisa Ann Schleipfer At last week's ACM Awards, Country Music star Keith Urban and wife Nicole Kidman revealed they have learned the sex of their unborn child, but they’re not telling us. "I'm not saying," was Urban’s final word on the red carpet. Kidman glowed saying, "We're very excited. We're very pregnant and good." Meanwhile, rumors are starting to surface that the expecting mum has done a nude photo shoot of her pregnancy for Vanity Fair. No official reports have been made, but if rumors are true, Kidman would be following in the footsteps of Demi Moore, Gwenyth Paltrow and even Britney Spears, all who have done nude photo shoots late in their pregnancies.
