Actress Lindsay Lohan may have stepped into it again, this time allegedly getting into a physical altercation with a staffer at the Betty Ford Clinic.
The Palm Desert Police Department is now investigating an incident that occurred Dec. 12, after the troubled starlet and her roommates reportedly went to a bar and returned in the wee morning hours, TMZ reports.
Upon arriving at the clinic, Lohan got into a "hand-to-hand" confrontation with a staffer, who now wants to press charges for criminal battery, according to authorities.
Lohan could end up spending six months in jail over this latest set back, stemming from her DUI arrest in 2007. Her probation doesn't end until August 2011.
