Michael Lohan says he's moving to California to open a drug and alcohol rehabilitation center, he told RadarOnline.com.

"Yes, it's, true, I'll be running it," Lohan told us in an exclusive interview. "I think it's time that Dina and I both step out of the media for a while, and for me that means getting back to what I know best -- helping people with addiction."

Michael says the rehab center is being backed by "a really well known person" but says he can't disclose yet who it is.
