"American Idol" winner Phillip Phillips' mother, Sheryl Phillips, was arrested for DUI this morning according to a TMZ report.

The report says cops pulled her over in Albany, Ga., which is near Phillip's hometown. "According to law enforcement, officers administered a field sobriety test and Sheryl was unable to complete it," the report adds.

It cites an anonymous "source close to the family" who says Phillip's parents split up last week.
