Lindsay Lohan's dad Michael has blasted producers of a new porn movie spoofing the actress and her on/off relationship with Samantha Ronson.

Untrue Hollywood Stories: Lindsay Lohan sees look-a-like Scarlett Fay romping with legendary XXX actor Ron Jeremy while Ronson's character, played by porn star Dylan Ryan, looks on.

The parody, produced by Hustler magazine, also sees 'Lohan' dressed up as a naughty schoolgirl, throwing back champagne and sharing a steamy kiss with 'Ronson'.

But the 23-year-old Mean Girls star's outspoken father Michael has lashed out at movie bosses for taking advantage of his daughter's troubled reputation.

He tells the New York Post, "That's disgusting! I don't want to see it. We can't stop it, but I wish she would get herself out of this situation where she puts herself in the limelight where people are going to pick on her."
