Lindsay Lohan is doing everything she can to stay sober, according to her father.

Michael Lohan - who has battled alcohol issues himself in the past -has been attending Alcoholics Anonymous (AA) meetings with his 24-year-old troubled daughter since she was released from rehab earlier this month and is delighted with her progress.

He told gossip website Hollyscoop: "We went to an AA meeting last night then went home and had a quiet night.

"She changed back to the girl she used to be. When she was at her best - literally. She's done a 180 and I'm very proud of her."

Lindsay moved into a four-bedroom home in Venice, California - which is situated next to her former girlfriend Samantha Ronson's house - alone after being released from the Betty Ford Clinic but Michael isn't worried that this will affect her recovery.

He said: "I don't think it matters where someone lives because you're going to find the elements of addiction, the wrong people, and places no matter where you are."

Even though she has left the rehab facility, Lindsay will still be subject to random drug and alcohol testing with a psychiatrist until a court hearing on February 24.
