After playing a gig at Lavo in August 2011, Samantha tried to take the memories of her night in Las Vegas back to L.A. with her. But cops outside Baker, Calif., seemed to have a problem with that when they arrested her for DUI. "When she was stopped, she showed signs of being impaired," a police officer told Us Weekly. "[The officer] gave her balance tests and she showed signs of alcohol intoxication." However, Sam was cooperative and "admitted she had consumed alcohol early [that] morning or late last night." We guess someone didn't learn anything from her relationship with Lindsay Lohan.
