“I want my daughter off prescription medication,” Michael Lohan told Access Hollywood. “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.”

In response to her father’s accusations, Lindsay Lohan posted on Twitter Friday night: “The next shopping spree I’m going on is for a new last name!!!” Calling Michael Lohan a “lunatic,” Lohan said her father has “never been around in my life other than when he’d threaten me&my family.”

“He should be where he has always put himself after verbally abusing and physically abusing people all my life-behind bars,” Lohan said. “Its so sad to get a phone call from my baby sister just now asking, ‘why is daddy doing this?’ Through tears. He’s crossed the lines&hurt me&my family 4 the last time… So much for having a ‘dad’….. I’m going to spend some time with the ones that love me&i love now.”
