Lindsay Lohan will move in with her mother after leaving rehab.

The 27-year-old actress is determined to clean up her act and wants to live with her mum Dina after completing her 90-days of court-ordered rehabilitation on July 31 - which she was forced to complete as part of a plea deal she struck to avoid jail after lying to police officers about driving in a car accident last year.

Dina said: ''She will definitely start back at home with all of us.''

The 'Mean Girls' star spent her birthday on July 2 without her family and instead had a low-key celebration ''with all the kids at rehab'' at Cliffside rehab facility in Malibu.

Dina insisted: ''We couldn't visit because it fell during the week but we mailed her cards and gifts. We're going to work it out to all go visit her again, and then we're planning a pool party.''

It was previously reported Lindsay is determined not to fall back into her old partying lifestyle in Los Angeles or New York City, and is planning on going into hiding after rehab to maintain her sobriety.

The redhead - who has suffered alcohol and drug issues in the past - is said to be responding well to the 12-step programme and has been telling friends she ''wants to get back to her true self''.
