Amy Winehouse's stint in rehab didn't last very long.

The 27-year-old singer has checked out of Priory Clinic after one week, her rep confirms to the Associated Press; Winehouse will now undergo an outpatient treatment program.

When Winehouse entered treatment on May 25, her rep told Us Weekly that the singer wanted "to be ready for performances in Europe this summer."

This isn't the first time Winehouse has been in rehab: the "Valerie" singer sought treatment in January 2008 to overcome her drug and alcohol addictions.
