Lindsay Lohan has been moved to a sober house.

The troubled actress has successfully completed her first phase of treatment at the Betty Ford rehabilitation centre so is now staying at a property near the main facility, where she is receiving "residential day treatments".

While she is there, Lindsay is able to enjoy supervised activities as well as doing her own grocery shopping.

A Betty Ford representative said of the sober house: "It's a buddy system and no patient is allowed to go out by themselves."

However, Lindsay's family won't be able to visit her there as meetings can only take place in the main house and on Sunday afternoons.

Lindsay's mother Dina has revealed her daughter is doing well in the clinic and believes she is finally on the road to recovery.

She said: "She's just a different person. She's been in a couple facilities, but this one to me has really changed her."

Dina - who is divorced from Lindsay's father Michael Lohan - also admitted Lindsay, 24, is an addict, something she has always denied in the past.

When asked why she hadn't admitted it before, Dina told US TV programme 'Today Show': "That was for Lindsay to admit. As a mother it wasn't for me to come to tell the world about her problem. That was for her to do. I wasn't in denial.

"We take it one day at a time. Addiction is difficult. I don't know. I don't have a crystal ball. I pray hard ... We can only be positive and look to the future to help other families."

Lindsay was ordered by a Los Angeles court to stay in rehab until January 3 2011 after she tested positive for cocaine during a random drug test in September.
