Frances Bean Cobain almost missed her train. The daughter of Courtney Love and Kurt Cobain was in line to take Amtrak from Boston to New York Sunday when she was told her reservation hadn’t been paid for. “She caused a huge backup on the line because she refused to pay herself,” says a spy. “She was causing a scene and saying her name loudly to the guy behind the counter, but he had no idea who she was. Finally, she got out of line to call her business manager, who paid for her ticket.”
