Britney Spears looked genuinely chuffed with life yesterday as she flashed a huge beaming smile for the awaiting paps. With blonde tousled hair, the troubled pop star bounced from her regular workout at Bally's Gym in a cute pink and blue outfit.Everyone noted that her sunny disposition may be due to the fact that yesterday a court awarded her more liberal visitation rights with her two sons, Sean Preston and Jayden James.
