After just one week of treatment, Amy Winehouse has checked out of rehab, the Associated Press reports. The singer was seeking treatment in London.

Winehouse's rep, Chris Goodman said she was looking forward to touring Europe this summer and "raring to go." He also said the 27-year-old will continue her treatment at the Priory Clinic as an outpatient.

The Priory Clinic offers treatment for a variety of psychiatric problems in addition to drug and alcohol addiction. But her rep did not reveal why she was there.

Winehouse has a well-documented history of drug and alcohol abuse as well as self-destructive behavior since bursting into the limelight in 2007 with her Grammy-winning sophomore album 'Back to Black'.
