Lindsay Lohan was once again happy to smile for the cameras as she filled up her car at a gas station in LA last night. One of her friends was behind the wheel, and LL's ex Samantha Ronson has also been spotted visiting both while Lindsay was getting treatment and since she was released. She looked equally happy earlier in the day at an appointment after her first evening out and about on Wednesday. Dina Lohan told Matt Lauer that LL would be moving out of California upon her release from rehab, but the actress has to stay in the state for the next few months as she completes her mandated treatment and random drug testing. Friends are apparently already worried about Lindsay staying on the right path, but for now she's off the red carpets, out of the spotlight, and looking upbeat about her freedom.
