Troubled Hollywood starlet Lindsay Lohan is in the clear over reports she drank alcohol at the MTV Movie Awards, her lawyer told TMZ Friday.

Shawn Chapman Holley said her client recorded a negative alcohol urine test at LA's County Probation Department at 10am local time on Monday June 7 -- just hours after her alcohol monitoring SCRAM bracelet generated a positive reading following the awards.

Sources connected with the probation department confirmed to TMZ that the results from the urine test were good enough for the 23-year-old star to be in compliance with the terms of her probation.

But a contrary report on RadarOnline Friday claimed that Lohan had indeed been drinking -- and that her blood alcohol level ranged from .03 to .04 from midnight to 3 a.m. on the night of the awards.

"There was absolutely no doubt that Lindsay was drinking, and the report that the alcohol monitoring service provided ... was very detailed and extremely reliable," a source close to the situation told the entertainment website.

A California judge issued a warrant for Lohan's arrest after the SCRAM alert, but it was recalled an hour later when her bondsman posted bail.

The "Mean Girls" actress claimed on Twitter that it was “physically impossible” for the ankle bracelet to have given a positive report.

“My scram wasn't set off. It's physically impossible considering I've nothing for it to go off. All of these false reports are absolutely wrong,” she wrote.

Lohan is next due in court on July 6, where she could face jail if found to be in violation of any terms of her probation, including regular alcohol education classes.
