AceShowbiz - Lindsay Lohan's lawyer has fired back at reports suggesting the actress drank alcohol and used drugs during her four-month stint at the Betty Ford Clinic rehab facility. If true, Lohan, who checked out of rehab on Monday, January 3, faces jail time for again violating the terms of her probation, but attorney Shawn Chapman Holley insists her client was clean throughout her stay.

Sources tell the Los Angeles Times newspaper that Riverside County detectives believe Lohan may have violated her probation during an altercation with a staffer at the clinic by refusing to take an alcohol sobriety test.

A statement from Holley reads, "I had numerous conversations with Betty Ford counsellors and doctors over the course of Lindsay's treatment there and it was never suggested by anyone that she ever drank or used drugs. Her discharge letter from the facility is totally consistent with that."

Lohan appears to be concentrating on getting healthy now she's no longer in rehab - after moving into her new Venice, California home, the actress has been spotted working out at a West Hollywood gym.
