London: ``Mean Girl`` star Lindsay Lohan`s estranged father has revealed that troubled actress is not the girl he brought up.
Michael Lohan recently discovered the medical prescription his daughter is following while under probation.
Lohan has been sentenced to serve 90-days in jail for violating the terms of her probation.
"This is not the girl I raised. She`s gotta start all over again. Get off the prescription meds," the Daily Express quoted Michael as telling US TV show Access Hollywood.
The pills the actress is popping includes medication for depression, attention deficit hyperactivity disorder and acid reflux.
"That combination will kill her," said the worried father insisting that the all the pills she is taking are needless.
"She was never on medication up to the pinnacle of Mean Girls. My wife Dina and I got divorced, Lindsay started partying and going on medication... (and) she never did a serious movie again... Her life went into a downward spiral," he added.
Moreover, he blames his ex-wife for enabling his daughter`s prescription drug use.
"I thought she was the best mother when the kids were growing up. She`s turned out to be the worst mother on the planet... She doesn`t think Lindsay has a problem," he said.
