Michael Lohan's former mistress, Kristi Kaufmann, went public with claims he's the father of her daughter Ashley in 2008 and the born again Christian has vehemently denied the allegations.

He told TMZ.com Kaufmann changed the child's birth certificate to feature his last name.

Now, Lohan is negotiating a deal with producers of U.S. talk show Maury Povich, to undergo DNA testing for a TV segment which will prove once and for all whether or not he fathered a lovechild.

When the matter first surfaced two years ago, when Kaufmann's child was 13, the DNA tests were delayed - but Lohan seemed keen to resolve the whole thing, stating, "I'll do whatever it takes to find out. Everyone will know the truth soon."
