Lindsay Lohan SCRAMThe alcohol-monitoring bracelet fitted around Lindsay Lohan's ankle went off Sunday evening at an awards show after-party, and if is determined there was alcohol in her system, the beleaguered actress could face jail time.

According to various reports, Lohan's SCRAM device was triggered during an MTV Movie Awards party. Whether she was actually drinking or the device was tampered with is unclear, but a source inside the company that makes SCRAM tells the New York Daily News that it "was not a mistake or malfunction."

The company, Alcohol Monitoring Systems, now must send their report to Judge Marsha Revel, and depending on its findings, may compel the court to order Lohan to appear -- where she could be slapped with 180 days in jail.
