Oh, no! Britney Spears was caught driving very erratically this week - scaring everyone around her! In footage obtained by DailyMail.com, the pop star hit up the Thousand Oaks restaurant Red-O on Wednesday night, where she reportedly ordered a quesadilla from the "happy hour" menu before raising a glass to toast the entire restaurant. Throughout her meal, onlookers claimed her top slipped off her shoulder and she knocked glasses and other items to the floor. When she went to leave, a female friend allegedly had to help guide her out the door because she was struggling with her footing. Uh oh..
