Michael Lohan Planning A Lindsay Intervention

Lindsay Lohan and her dad Michael have been tweeting about their longstanding feud, which reached a new nadir last week when Michael threatened to "end" Lindsay.

Now Michael tells x17.com that he plans to get Lindsay into rehab, even if he's the only person on board with this plan:

"Since I found out what a horrible way Lindsay is in, and after finding out how drastic it has become, I immediately contacted the necessary people in Lindsay's circle, including her attorney as well as an attorney of my own. It is nobody's business when or how it will happen. Hopefully Lindsay, her attorney and the 'people' who influence her, will be on board. If not, the process will continue without them. I promise that!"

Michael said he tried to plan an intervention for Easter weekend, but the holiday got in the way of people's schedules. He also threw some blame at Lindsay's lawyer.

"Shawn Chapman Holly tells me one thing and does and says another," he said. "Meanwhile she says and admits privately how bad Lindsay is in but she does nothing. Instead, she says she has a legal responsibility toward Lindsay. So does this mean that she should watch Lindsay die."

Holly fired back: "Michael Lohan's conduct with respect to his daughter and to the media speaks for itself. I represent Miss Lohan and will continue to protect her personal and legal interests to the very best of my ability."
