Lindsay Lohan's father Michael has served up another helping of bitter words for Samantha Ronson.

After a series of run-ins with couple about their love affair, the outspoken dad seems more than happy to risk his relationship with Lindsay by unleashing his poisonous tongue against her girlfriend once again.

In an email published on X17, Michael writes:

There is a lot more to Samantha than meets the eye! Not that what we see is soooo pleasing anyway!I I mean, what's with this ...."person"??? Look at the way she "dresses"? Once more, she uses her middle finger more than she uses words! Personally, I think she is dark, hideous and a disgusting representation of humanity!

Have you ever seen her apartment? For God's sake, when she runs out of toilet paper she tells people to use the cardboard roll. (I was told this first hand).
I heard and know more about Samantha than you can imagine. Yet, while I haven't exposed her, I know that God will.

Despite the absence of Michael's blessing, the couple are said to be planning to tie the knot later this year.
