Lindsay Lohan has claimed that her father threatened to kill her mother.

The “Mean Girls” actress, who is seeking a restraining order from dad Michael Lohan, is furious with him for leaking old phone calls between herself and him to the press and has hit back with some new claims.

She wrote on her Twitter page: "He's a deadbeat dad. He's disgusting to do this, he needs help."

Speaking about his relationship with ex-wife Dina Lohan, Lindsay claims she didn’t leave him, despite an abusive relationship, because she was terrified he would take her life.

“She blames herself for staying w/him for so long. She didn’t leave because he always threatened to kill her if she did (sic)” she said.

In one of the phone call tapes released by Michael, his eldest daughter can be heard sobbing: "No one cares about me . . . It's about how they feel, not how I feel. It's not about me. It's never been about me, unless I fight for it."

Although she is furious about the leaked calls, the 23-year-old actress has vowed to move on with her life and doesn’t want her father to be a part of it.

She wrote: "that I even have to share this w/everyone, but I haven't had a real relationship w/Michael Sr. In years . . . I just hope I can show others how to be strong through times and to be able to stand up for yourself and loved ones no matter what! (sic)"

Michael Lohan has previously claimed he is only speaking out about his daughter because he is concerned she is addicted to prescription drugs and wants her to go to rehab.

"I want my daughter off prescription medication,” he said. “She never needed it in her life...I'm not going to watch my daughter die. Hate me now, but you love me more later because I'm gonna turn her life around."
