Nicole Kidman and Keith Urban have separated after nearly 20 years together, a source told the BBC. The Oscar-winning actress and four-time Grammy winning country singer have been married since June 2006. TMZ first reported the news and cited sources who said the pair had been living apart since the summer and Kidman does not want the separation. Kidman and Urban, who both grew up in Australia, have weathered ups and downs over their nearly two decades together. Kidman and several of his close friends staged an intervention that Urban said changed his life.
