Nicole shows off her


Nicole Kidman has been about the thinnest pregnant woman around with most observers wondering when the Oscar winner might start showing. They got their answer last night when the mom-to-be proudly showed off her baby bump in a gray YSL dress. Nicole attended the 43rd Annual Academy of Country Music Awards in Las Vegas, where she was supporting hubby Keith Urban. The glowing Nicole and country crooner Keith are said to be welcoming their baby this summer.
