Lindsay Lohan was spotted at the American Red Cross blood services facility in an LA suburb yesterday. The recently rehabbed actress is fulfilling part of her plea deal for her DUI conviction last August. Lindsay was sentenced to a mandatory minimum of four days in jail, with 10 days of community service in lieu of two days in prison. She was also given a one-day credit of time served from her July arrest, leaving just 24 hours in jail, which she must complete by January. Lindsay arrived at the Red Cross at noon yesterday and left around 7 p.m., with a book titled Blood under her arm.
