KEITH URBAN RUNS BACK TO REHAB AFTER MEETING WITH NICOLE KIDMAN

Nicole Kidman's reunion with husband Keith Urban is to be short-lived,because he is only on leave from rehab.The couple met for brunch in Los Angeles on Sunday, but, contrary to reports, the country singer will not be returning home to Nashville and must go back to the Betty Ford Centre in Palm Springs to resume his treatment for alcohol abuse. Urban's representative said: "At this stage in treatment patients are occasionally allowed to leave for short periods of time."Keith is not out of rehab and is not back home in Nashville." Urban, 39, checked into rehab on October 19, where he was expected to stay for 40 days, saying in a statement: "I deeply regret the hurt this has caused Nicole and the ones that love and support me."Kidman, 39, last visited her husband - who has previously been treated for cocaine and alcohol addiction - at the clinic on November 12. It is thought that one requisite of the couple's prenuptial agreement was that Urban would seek treatment immediately if he began drinking again.
