According to the Today Show, Keith Urban cannot even find the words to express the lessons that he and his wife have learned while he was being treated at a rehabilitation clinic.

The pair had barely been married four months when Keith made the decision to seek help for his problems with alcohol, but Nicole stood by him. The two actors have learned a lot from their experiences of going through and supporting a loved one through rehab.  The Tonight I Want to Cry singer said, "We've been through a lot, and she's been extraordinary." 

Keith was treated for an addiction to cocaine in 1998 and was admitted to rehab again last year for alcoholism.

Urban, 39, concluded "I'M really grateful for the support I got around me."
