Lindsay Lohan has been advised to spend another 30 days in rehab.
The 27-year-old actress has been urged to extend her stay at the Cliffside facility in Malibu beyond July 31 - which is when she completes her 90 days of court-ordered rehabilitation - because doctors want to make sure she makes a full recovery from her substance abuse issues.
However, the troubled star has told pals she won't be staying a minute longer than she has to.
A source told RadarOnline.com: "Lindsay has been doing so well at Cliffside. She is responding very, very well to treatment.
"The treatment team wants Lindsay to stay for at least another 30 days, because she didn't do her entire 90 days at Cliffside. Someone with her addiction and psychiatric issues needs extensive treatment and 90 days just isn't enough.
"She is in a really good place right now, but her doctors want that to continue."
'The Canyons' star - who has battled alcohol and drug abuse in the past - was forced to spend three months in rehab as part of a deal she struck to avoid jail after lying to police officers about driving in a car accident last year.
The actress 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".
The actress is determined to kick her addiction and is planning on moving in with her mother, Dina, when she is released from the clinic in a bid to clean up her act.
Dina said: "She will definitely start back at home with all of us."
