Dad of the year Michael Lohan at first demanded $100,000 for his story and secret recordings of daughter Lindsay and wife Dina, sources told Page Six.

Lohan had been shopping his tapes around TV networks but was turned down, and eventually struck a deal with RadarOnline.com to reveal the tapes for free, followed by a paid interview.

And despite legal threats from Dina to stop revealing strictly private family conversations, Michael said he would carry on revealing more tapes until he gets Lindsay — who he claims is addicted to prescription drugs — into rehab.

A source told us, “Michael initially asked for a large fee — six figures — for the tapes of Lindsay and Dina, but he didn’t get any takers. Radar Online also refused to pay for the tapes, so in the end he agreed to a deal to release the recordings for no fee, but giving him the exposure he needs with a paid interview.”

Michael told us that a six-figure demand for the tapes “was a complete lie,” but when asked if he was paid for his interview, he said, “That’s in the hands of my lawyers. They deal with that.”

He insisted, “This isn’t about money or getting paid, it’s about saving my daughter.”

And he said his ex-wife’s plan to have him prosecuted was a waste of time because “all the recordings were done when both Dina and Lindsay were in New York,” where it’s legal to tape phone calls without informing the other party.

But his campaign seems to be having the opposite effect on his defiant daughter, who jetted back from Morocco to LA late Thursday and immediately went out partying at racy club Voyeur until the early hours of Friday morning.

Michael said he wouldn’t abandon his plan despite heavy criticism from Lindsay and Dina. He said, “I have more recordings which will further back up what I have said so far. I will release them. I will not stop until Lindsay goes to rehab.”
