When Mischa Barton got on the train to Cuckootown we thought she joined the ranks of Britney Spears and Mariah Carey. Not really, because people seemed to actually care about their public descent into madness. Is the celeb meltdown passe?

Mischa Barton was supposed to be in New York tonight to attend the premiere her of her new movie, Homecoming, which was directed by Morgan Freeman. However, she won't be attending after cops were called to her home last night.
