Hollywood actress Lindsay Lohan has successfully passed two drug tests and is trying her best to stay clean.
The "Mean Girls" actress was ordered by a court for random screening as part of the conditions of her recent probation hearing for driving under the influence of alcohol, reports femalefirst.co.uk.
"She (Lohan) is clear of illegal substances. She has already taken two tests and passed both," a source said.
The 23-year-old was also ordered by the court to wear a SCRAM (Secure Continuous Remote Alcohol Monitor) bracelet on her ankle to monitor her body's alcohol levels every 30 minutes.
