Lindsay Lohan is not addicted to prescription drugs
The -Mean Girls- actress - whose father Michael has repeatedly insisted she has a problem with legal substances - has amazed doctors at the UCLA Medical Center with her responses to treatment, leading them to recommend she only stay in the facility for a maximum of 30 days, rather than the 90 days she was ordered to spend there by a court.
A source told X17online: "Lindsay may have taken prescription medication, but she doesn`t have `an addiction`.
"She`s been through detox, but had no withdrawal symptoms, so doctors don`t believe her issues were as serious as they were led to believe initially."
In addition, the insider - who also revealed the actress` former girlfriend Samantha Ronson visits her "four or five times a week" - says the 24-year-old star has been misdiagnosed with psychological problems, claiming Lindsay`s troubles stem from the difficult relationship her parents Dina and Michael have with one another.
The source added: "The only thing Lindsay suffers from is having two narcissistic parents and she fills the void by hooking up with destructive people and bad habits.
"Her mom Dina bad-talked Michael for so long that Lindsay and all her siblings ended up disliking him but she needed something to fill the father void, so she started acting out."
A court hearing has been scheduled for August 25 to discuss whether Lindsay should be released from rehab early.
The troubled star was sentenced to 90 days in prison and a 90-day rehab stint for breaching the terms of her probation set for a 2007 driving under the influence (DUI) conviction.
She was released from jail after serving just 13 days of her sentence.
