Lindsay Lohan may be trying to clean up her act. After a week of partying with Paris Hilton and Britney Spears, Lohan was seen at an AA meeting near her LA apartment at 7:30 yesterday morning. "She has attended several meetings and has hopefully decided to turn her life around - this time for good," a friend of the Bobby actress says. "She is out of control." Lohan allegedly skipped out on a family Thanksgiving because "someone would force an intervention on her," and friends of the starlet hope "she will really get serious about getting sober. And drop out of the limelight for a while."
