Once a deadbeat dad, ALWAYS a deadbeat dad … so says one of Michael Lohan”s baby mamas … who says it”s a lesson Kate Major is about to learn the hard way.

our sources spoke with Kristi Horn – who has a 17-year-old daughter named Ashley with Lohan. Horn tells us Michael isn”t just an absentee father … he also owes her more than $300k in back child support.

And Horn says there”s a ZERO PERCENT chance MiLo changes his ways with the new kid on the way.

 “This is a freaking train wreck … here we go again,” Horn says.

“I just feel so bad for Kate. She’s going to be a single mother eventually … he’s going to leave her to raise their child alone like he did to Dina and I.”

Maybe, maybe not … but probably maybe.
