Lindsay Lohan Out of Rehab, Into the Gym (PHOTOS)

Lindsay's Troubles
A timeline through Lindsday Lohan's tough times.
Lindsay Lohan was let loose from Betty Ford Center on Monday, and the actress immediately dipped back into one of her old habits – working out at the gym. Seen here, LiLo appears ecstatic to be surrounded by paparazzi once more.

But her excitement may be short-lived, as People is now reporting that Sheriff’s investigators want Lohan formally charged with battery against a Betty Ford worker who she allegedly fought during her stay. If true, it would constitute another violation of her probation, and according to a Beverly Hills judge, it would mean jail again.
