Spokesman Craig Harvey says the actress was 40 minutes late to an orientation session scheduled for 8 a.m. Thursday, but will be given another chance to show up on time on Friday.
Lohan tried to report to the morgue one day after she was scolded by a judge for being terminated from a community service assignment at a women's shelter. The hearing ended with the 25-year-old actress' probation being revoked and her being led from court in handcuffs.
She later posted $100,000 bail and was released.
Her spokesman Steve Honig says the actress' tardiness was partially because she didn't know which entrance to the facility to use.
