Britney Spears had a huge public fight the other night with her boyfriend, Jason Trawick, at the Mondrian hotel in Los Angeles. The singer stormed out after she and Trawick -- who recently quit being the pop tart's manager in order to concentrate on being her boyfriend -- started arguing over dinner on Thursday. A spy told Page Six, "Britney was rude to the waitress and then started arguing with Jason, saying she'd had enough. He was trying to calm her down, but she wasn't in the mood. They had been sit ting down for dinner, but just over 30 minutes into the meal, Britney de cided she wanted to leave. She headed out of a back door of the hotel, with Jason following, still trying to calm her down. She looked furious. It's clear there is trouble in paradise" Spears' rep declined to comment.
