Keith Urban was only married to Nicole Kidman for four months when he checked into rehab in October 2006 for drug and alcohol addiction.
"[I thought] 'Surely, let's give it a few years so we've got some solidity, because this kind of thing could tear us apart," Urban told Oprah Winfrey on her show Monday. "This could just destroy us."
Urban, who was hooked on cocaine and other substances, revealed that it was Kidman and some close friends who staged the intervention. The 2006 trip to rehab was his third in eight years. "I had to make a decision which road I was going to take, once and for all. I'd been at that crossroads before and always taken the wrong road," he said.
Urban and Kidman have a daughter, Sunday Rose, and they live in Nashville, Tenn. Of living outside the Hollywood bubble, Kidman told Winfrey, "Some people like the much higher sort of more glamorous lifestyle. For us, we just prefer a much quieter, private [life]."
