Keith Urban and Nicole Kidman

Los Angeles, Oct. 21 (Reuters): Country music star Keith Urban has checked into a rehabilitation centre, with actress-wife Nicole Kidman “at his side”, his spokesman said on Friday.

“I deeply regret the hurt this has caused Nicole and the ones that love and support me,” the singer said in a statement released through his publicist.

The 38-year-old performer, who won a 2005 Grammy Award for his hit You’ll Think of Me, did not disclose the location of the centre or the nature of his treatment.

He has acknowledged struggles with cocaine and alcohol in the past.

“One can never let one’s guard down on recovery and I’m afraid that I have,” Urban said in the statement. “With the strength and unwavering support I am blessed to have from my wife, family and friends, I am determined and resolved to a positive outcome.”

On his website, the New Zealand-born country superstar told fans that he was “calm and optimistic about the future and finally coming to terms with the reality of my condition”.

Kidman, who won an Academy Award for portraying Virginia Woolf in the 2002 film The Hours, cancelled a round of interviews to promote her upcoming film Fur.

Publicist Paul Freundlich said because of the treatment Urban would suspend appearances for the release of his CD Love, Pain & The Whole Crazy Thing, which is scheduled to hit stores on November 7.

Freundlich said Urban “voluntarily admitted himself to a treatment rehabilitation centre last night with his wife by his side”.
