Lindsay Lohan is reportedly facing up to eight months in jail.
The Liz & Dick star is tipped to have her probation revoked in court today with the case relating to her car crash in June, in which she is accused of lying to police about being the driver, set to begin.
It could result in her being sentenced to 245 days behind bars.
Law enforcement sources told gossip website TMZ.com that the Los Angeles City Attorney is "out for blood" and will file papers asking that Lohan's probation be revoked.
They expect the 26-year-old actress to be formally charged with lying and reckless driving tomorrow, after which the judge is likely to revoke her probation relating to her prior jewellery theft and set a date for a hearing to decide if she violated her probation by breaking the law again.
