Following an alleged mental breakdown and involuntary hospitalisation in July, it seems Mischa Barton still isn’t back to normal. Insiders on the set of the actress’ latest TV project, ‘The Beautiful Life’, say the former star of ‘The oC’ is alienating members of both cast and crew with her diva behaviour, which is holding up production. one source reports, “She was getting snippy with the director and kept demanding that someone make instant coffee for her. often, she’ll stare at the coffee for minutes at a time and say, ‘Who will fix my coffee? I need someone to fix my coffee.'”
