Lindsay Lohan claims she is in a "great place".

The troubled actress - who is currently staying in a sober living facility ahead of beginning a 90-day jail term for breaching probation - has blasted her estranged father Michael Lohan for his comments on her life and has warned him to stay away from her.

She tweeted: "I don't want my ex-father anywhere near me no matter where I am. He is crazy and scares me.

"I don't want Michael Lohan Sr. anywhere near me, no matter where I am. I am in a great place and he only brings negativity in my world."

Lindsay's comments came after Michael blasted her new lawyer Robert Shapiro over a "conflict of interests".

Michael believes the lawyer should do more to appeal the 24-year-old star's prison sentence instead of encouraging her to enter the facility which he founded in memory of his son, who died of a drugs overdose.

Michael - who has repeatedly claimed Lindsay is addicted to prescription drugs - told E! News: "It's a conflict of interest if he's putting her in his own sober house but not doing anything for her legally.

"But when you have an attorney like Robert Shapiro, who went through so much with his own son and knows the effects of prescription medications, it doesn't make sense that he did nothing to appeal her case and get her off the meds before she goes to jail.

"Everyone knows that when you go into the jail or prison system, if you're on prescriptions written by a doctor, they give them to you in prison. It's a continuous cycle. Here you are punishing a girl because she has a drug problem, or at least for things that resulted from a drug problem and not doing anything to fix it.

"I'm very upset that Robert Shapiro did nothing to appeal the case."

Lindsay is due to start her prison sentence - which stems from a breach of probation conditions she was set following her 2007 conviction for driving under the influence (DUI) - tomorrow (20.07.10).
