Mischa Barton is a trooper. Mischa was partying so hard with pals Jamie-Lynn Sigler and Kirsten Dunst at NYC hotspot Anchor last Thursday that she had to run outside and vomit. Her pal Jamie ran out after her and the pair came back in the club laughing and continued to party until after 3am. That is some serious commitment right there. Maybe is Mischa was that devoted to her craft she wouldn’t be unemployed. Just a thought.
