Lindsay Lohan could be facing almost a year-and-a-half in jail.

The troubled actress is set to attend court on Wednesday (19.10.11) to see whether she faces a prison sentence after she allegedly skipped court-ordered therapy sessions, according to gossip website TMZ.

Judge Stephanie Sautner recently berated the 25-year-old star for failing to find a therapist for weekly sessions, which was part of her sentence for stealing a $2,500 necklace from a boutique in January.

But Lindsay - who previously served 35 days under house arrest for the offence - claims to have carried out her therapy sessions over the phone.

She spent time in France last month doing a modeling job, but is said to have cleared the two-week trip with her probation officer - and she recently went to Italy, where she was unveiled as the new face of Philipp Plein.

Lindsay said: "Something important to know about this collection is that it's expressing something a little bit more edgy. And I think maybe people's perceptions of me have been kind of taken out of context just from what you see and read."
