Lindsay Lohan's relationship with estranged father Michael Lohan got even uglier on Nov. 4, when Michael released a series of secretly recorded audiotapes of conversations he had with Lindsay and her mother, Dina. But now Michael is doing an about-face.

"I will not release another audiotape about Lindsay," he tells Life & Style, claiming he leaked the tapes only to pressure Lindsay -- who he fears is abusing prescription drugs -- into a rehab facility. "I did it because I wanted Lindsay to know how I felt when I heard that tape. When I get a phone call at 2, 3, 4 or 5 in the morning from my daughter and she's in dire straits, I get very concerned."

On one recording, a hysterical Lindsay claimed, "No one cares about me." On another, Dina talked about Lindsay "cutting herself and hurting herself," while another disturbing recording exposed the troubled 23-year-old's apparent secret fling with Heath Ledger, who died of a drug overdose in 2008. Dina was livid after the tapes were released, saying, "The tapes were from a long time ago. For a father to stoop this low is unforgivable."
