The hospital where Jennifer Lopez will give birth has been practicing drills to prevent kidnapping attempts - but denies it has anything to do with the star's scheduled stay. Staff at North Shore Medical Center in Long Island, New York have been taking part in a Code Pink security drill, which involves locking down the hospital if a baby goes missing. But bosses have played down kidnap fears, insisting the timing of the drill was "coincidental". Lopez and husband Marc Antony are reportedly expecting twins.
