On Wednesday, with the stink of her larcenous photo shoot for OK! magazine still hanging in the air, Britney Spears displayed even more erratic behavior at the shoot for her new music video, reports the News of the World. After knocking back 20 or so of those vile-tasting Red Bulls while chain-smoking, Spears, in fishnets and skimpy leather vest, “threw a complete fit,” said an onlooker, when she became shy and “wobbly” trying to work the stripper pole and aggravated that there were extras in the scene with her, which led to her eventually dissolving into tears, squatting on the floor with her new puppy, and staring vacantly into space. She may have been rocking back and forth like a crazy person, we don’t know. The director had to wrap the day early and send home the crew of 100. “She just didn’t want to cooperate and was snotty and rude to everyone — behaving like a complete and utter spoiled brat,” said the onlooker. “It was embarrassing. She needs help fast.” Thank God no one was hurt. (Photos: Alec Byrne)
