Ex-husband,
Kevin Federline, has asked the courts to prohibit Britney Spears from
driving with their kids in the car. She is back at the wheel, but
looking very worried. The pop princess has had her hand on her forehead
and a serious look on her face as she waited at a red light in her
brand new 180 mph Mercedes SL65 AMG. She is in hot water after recently
being photographed going through a red light with the children in the
car.
