Jennifer Lopez has told hospital staff not to enter the room where she will give birth.The Do It Well singer is set to give birth to twins, her first children with husband Marc Anthony, later this month, and has asked staff at Long Island's North Shore Medical Center not to use the room until she arrives. A source told the New York Post newspaper: "There is a room, which even has a brown leather couch, that has been sitting empty for two weeks now. No-one is even allowed in there until she gets here. It's just sitting there for her." The hospital has reportedly prepared an entire suite for the 38-year-old star, complete with wooden flooring and a giant TV. It was recently revealed the hospital has been put on kidnap alert. Staff have been undertaking specialist 'Code Pink' drills to ensure they are prepared in case anyone attempts to snatch Jennifer's babies. A friend of the Monster-In-Law star said: "Jennifer has spoken so much about how excited she is about the birth that anyone who is considering a kidnapping knows how far she would be willing to go to get her babies back."
