John Stamos has been booked on charges of driving under the influence in Beverly Hills, reports AP. Police say they received calls about 7:45pm yesterday of an erratic driver and later stopped Stamos in his Mercedes. Authorities took the 51-year-old straight to the hospital because he seemed so "out of it," in the words of TMZ. He was alone in the car. The publicist for the Full House star hasn't publicly addressed the arrest yet. (More John Stamos stories.)
