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.
The insider suggested that the hearing will take place at the same time the actress stands trial on the criminal charges, and that even if she is found not guilty in the criminal case, the judge can still rule that she violated her probation.
Lindsay has been on probation since being found guilty of stealing a necklace in July 2011, for which she was sentenced to 120 days in prison and 480 hours of community service.
The actress is reportedly in the UK with her new love interest Max George from The Wanted, as she is not legally required to attend today's hearing.
