Lindsay Lohan began her community service at a Los Angeles blood donor centre on Monday (12.11.07).
The 'Mean Girls' star arrived at an American Red Cross blood services facility, located in an LA suburb, at noon and was greeted by staff in the parking lot.
She left at 7pm carrying a book entitled 'BLOOD' under one arm.
Lindsay was sentenced to the mandatory minimum of four days in jail after she was convicted of DUI (driving under the influence) for the second time, but prosecutors agreed to reduce this to just two days if she served 10 days of community service.
The 21-year-old actress has already served one day after the authorities gave her credit for the time she spent in custody following her July arrest.
She has until January to complete the remaining 24 hours of her jail
sentence.
Lindsay - who checked out of Utah's Cirque Lodge rehab centre on October 5 after a stay of over two months - was also placed on three years probation and must complete an 18-month alcohol education programme as part of her plea bargain.
