Brad Pitt says he and Angelina Jolie are going to need a bigger bed - for their expanding brood. "We're not done," Pitt told the Associated Press. "They say, 'Any plans for a fifth?' And I say, 'And a sixth, and a seventh, and an eighth, and a ninth.' That's my answer." Pitt added, "We also made a 9-foot-wide bed" that fits him, Jolie and all four children. "Just big enough. One more and we'll have to go to 11 feet..." The Assassination of Jesse James star told USA Today, "We just take turns and make sure we keep the family together. It's impossible for us. We're run out of every major city. There's just too many paparazzi. There's always cameras in the kids' faces, yelling their names. Angie gets out of the car, and they take the camera down to the curb and shoot up [her skirt]. It's unbelievable...there's a constant negotiation in how to survive and how to maintain a family life." Pitt says he can tell when cameramen are lurking even when he can't see them. "You develop radar. Like I know when there's someone in the bushes 300 yards away shooting," he says. "I know to recognize that feeling." Pit admits he's concerned about "how to survive and how to maintain a family life." "I understand the essence of paranoia," he says. "I understand being hunted, to some degree. It's rare, but there are imbalanced people out there. I've had break-ins in the house. I've had some of these abnormal incidents that can be a bit frightening." Pitt may be be referring in part to an incident at the Toronto Film Fest last week, when his and Jolie's car was swarmed with people. According to one gossip columnist, "People who were driving down on other streets left their cars and ran to see them. Seven people jumped on their car... People were holding up their cellphones [to take pictures]. This woman appears out of nowhere, runs up with her child, and was pushing her child up against the [moving] car. The lady was like, 'I want my baby to see Brad Pitt.'" Sound imbalanced?
