Lohan, 21, has now been warned that if she does not stay clean she will be thrown out of the centre.

This could be very serious for the star.

Only last week she pleaded no contest to drink-driving and possessing cocaine and was sentenced to just one day in jail.

Part of her plea bargain hinges on her completing the rehab programme or she could face a lengthy jail sentence.

A source said: "During the test Lindsay screamed and cursed at the medical director before storming out of the room."

According to reports it is not Lohan's first indiscretion since entering Cirque Lodge earlier this month.

She is said to have been caught having sex in a lavatory cubicle with a male patient, and reportedly refuses to do any chores.
