Keith Urban is celebrating 19 years of sobriety after his wife Nicole Kidman staged an intervention that changed his life. Urban opened up about his battle with addiction, recalling a voice inside his head warning him of a final crossroads. He credits Kidman for helping him make the decision to get clean in 2006, the same year they were married. Urban's music career also played a significant role in keeping him out of trouble, and he has since helped other artists struggling with addiction, like Brantley Gilbert.
