Lindsay Lohan plans to go into hiding after rehab to maintain her sobriety.

The troubled actress - who is in the middle of a 90-day court-ordered treatment as part of a plea deal after being found guilty of lying to the police - is reportedly terrified of relapsing into her partying ways when she leaves the Cliffside centre in Malibu, California, next month and is planning to move to a remote part of the United States where she won't be tempted to fall back into her old lifestyle.

The 'Mean Girls' star is determined not to move back to the Los Angeles or New York City, where she was often a regular on the party circuit, and is determined to turn her life around by living in a quiet part of the country ''where there are no paparazzi'', according to TMZ.

It's not known how long Lindsay, 26, plans to isolate herself away from the spotlight but sources close to the actress say she ''wants to get back to her true self''.

The former child star is currently being treated for addiction at the Cliffside facility - after transferring from the Betty Ford Clinic last month - and her 12-step programme is thought to be working, however, Lindsay is ''deathly afraid'' of relapsing once she exits rehab and readjusts to everyday life.

Lindsay was ordered to serve 90 days in rehab in lieu of jail time earlier this year after being found guilty of lying to the police about a car crash which occurred last summer. The actress claimed she wasn't driving during the incident, but authorities determined she was indeed behind the wheel.
