London, Jan 4 : Lindsay Lohan's father has launched another attack on the actress' girlfriend Samantha Ronson, calling her "a parasite".

Speaking exclusively to the News of the World, Michael - who has spoken of his disapproval of the pair's lesbian relationship in the past - has claimed that the DJ would not let his 22-year-old offspring visit her family over the festive period.

And also called Ronson a "parasite" who is a bad influence.

He said: "I was prompted to do this by people who know the truth and were tired of people slamming me for standing up for what is right.

"Sure, I made mistakes, but I paid the price and I am trying my best to turn it all around. The same thing I hope for Lindsay and anyone else, on any level, in her position.

"I remained silent for quite a long time but when Sam prompted Lindsay to write that blog and kept her away from her siblings during Christmas - that was the final straw."

The latest blow comes after Michael accused Samantha of writing a blog on Lindsay's MySpace page with barbed remarks about the fact he fathered an illegitimate daughter 14-years-ago.

"I am 99 per cent certain that Lindsay's blog was authored by Samantha," he added.

He even called the 31-year-old DJ a "dark, hideous and a disgusting representation of humanity." (ANI)
