Lindsay Lohan is screwing up again. She's been bounced from her court-ordered community service assignment for failing to follow rules, reports TMZ. She was ordered to serve 360 hours at the Downtown Women's Center in Los Angeles as probation in her shoplifting case. Lohan was supposed to show up, not be disruptive, and work at least four hours at a time. Sources say she completely blew off several work stints, and often disappeared after an hour when she did show up. She has been reassigned to community service at a local Red Cross. But she's due back in court next week, and the judge is likely to be irritated. (More Lindsay Lohan stories.)
