Kidman visits Keith in California rehab center

Oscar winner Nicole Kidman and new husband Keith Urban were spotted at the Betty Ford Center in Rancho Mirage, California, on Sunday, where Urban is seeking treatment.

The country singer entered rehab for alcoholism on Oct. 19 and media reports at the time said he was in a program near the couple's hometown of Nashville, not California.

source close to Kidman tells Us Weekly magazine, "Keith is expected to be in rehab for 35 to 40 days."

Prior celebrity clients at the center, where programs start at $21,000, include Johnny Cash and Anna Nicole Smith.

During his stay, he'll attend group therapy, lectures and spiritually focused programs.

Urban, 39, took home the Best Male Vocalist trophy at the Country Music Association Awards in Nashville on Monday night, and had pal Ronnie Dunn of country duo Brooks & Dunn read his acceptance speech, where he thanked his wife of four months for standing by his side.

The source adds, "They look forward to resuming their life together."
