LATEST: Troubled pop star Britney Spears has reportedly been lashing out at her rehab facility, demanding special food and refusing to pick up after herself. The TOXIC star has allegedly been behaving badly because she feels she has been forced into rehab by friends and family. A source tells American publication Star, "Britney has a seriously bad attitude problem. "She's been very demanding, acts like a 12-year-old and throws temper tantrums when she doesn't get what she wants. "She refuses to pick up after herself and even asked if she could hire a maid! "She's asking for this and that, special food, special everything and she's not that nice to anyone. "She keeps saying she is just sick from postpartum depression and that she does not have any real addiction problem, which is a joke. She has an addiction."
