Us Weekly reports that Britney Spears was recently enjoying a relatively mellow night out, smoking cigarettes and dancing with her girlfriends at the Los Angeles nightclub A.D. But around 1 A.M., Spears, 21,was told by her new bodyguard to call it a night. A witness revealed the singer responded, “I don’t want to go.” The replacement for Big Rob responded with a firm, “We’re going”. Then, without putting up a fight, Spears and her girlfriends quietly walked out of the club. With the early night, Spears was up bright and early to work out before hitting the recording studio.
