Keith Urban Tells Oprah: 'Nicole Saved Me' (VIDEO)

In an appearance that aired Monday, country music superstar Keith Urban told Oprah Winfrey that wife Nicole Kidman, "saved" his life by forcing him into drug rehab in 2006.

Urban tried to delay the rehab stint, fearing for his new marriage. "[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,'" he told the host, adding that he thought, "'This could just destroy us.'"

Undaunted, Kidman went on with the intervention.

"She made a decision to turn around and initiate, ultimately, this intervention. It was done in such a way that the love in that moment was such that, I was, put the cuffs on, let's go."

Urban said that he was addicted to "everything," though he struggled the most with alcohol and cocaine. With Kidman, he found himself able to replace substance with love.

"[There] was a huge hole in my life that was going to be filled by the right thing eventually or it was always going to be filled by the wrong thing," he remembered. "Ultimately for me, [the right thing is] love. ... Nic has taught me so much and brought so much to my life and opened my eyes in so many ways."
