Lindsay Lohan has passed up to 10 random drug and alcohol tests in the two weeks after she left the Betty Ford Center, RadarOnline.com has exclusively learned.
The 24-year-old Mean Girls star has had to submit to a series of spontaneous tests and has passed each one that she was forced to take so far, according to her father Michael.
"Lindsay is doing four or five tests a week and she has passed all of them with flying colors," Michael told RadarOnline.com, in an exclusive interview.
Lohan has been living a low key lifestyle since she was freed from the court ordered program and even spent Sunday night at home watching the Golden Globes on television.
"She's doing really great right now," Michael said.
"She is serious about staying healthy and is avoiding all the old things she used to do."
Lindsay's next court date is February 25, 2011, where she'll face Los Angeles Superior Court Judge Elden Fox.
As RadarOnline.com previously reported, her Palm Desert police report relating to an alleged assault of an ex-Betty Ford employee, was personally delivered to the judge and placed under seal.
"Judge Fox read the report and put it back in Lohan's file," one source close to the situation told RadarOnline.com.
"Right now, based on what he has read, he won't be taking any action against Lindsay."
