Michael Lohan’s latest Dina Lohan audio leak reveals an interesting claim: Heath Ledger for whatever reason, was doing it with Lindsay Lohan before he died. Dina said on a secretly recorded phone call with Michael,

She was dating Heath when he died. I don’t know if you know that, but I know cause I would drop her off and they were friends. Very, very close ok? So that f-cked her up.

We’re not quite sure why Michael didn’t reveal this golden ticket months ago, as it probably would have gotten him mountains of yummy publicity.

Also on today’s tape: Dina listing a number of Lindsay’s friends who died or had drug problems, and Dina revealing that she desperately wanted to hire someone to pretty much babysit Lindsay 24/7.
