Lohan caught taking drugs in rehab

Lindsay Lohan has been warned that she risks being thrown out of rehab after testing positive for drugs.

The Herbie: Fully Loaded actress was allegedly instructed to take a test after being caught with illegal substances at the Cirque Lodge facility in Utah.

A source is quoted as saying: "Lindsay got called into the director's office on August 15 and was questioned about drugs. When ordered to take a drug test, she reluctantly complied but screamed and cursed at the medical director before storming out the room.

"She was told that if she couldn't conform to the programme she'd have to leave."

Lohan reportedly angered authorities at the centre earlier this month by having sex with a male patient in a toilet cubicle.
