Samantha Ronson is a "wretched woman" who is "controlling" girlfriend Lindsay Lohan, says the actress' friend Joe Francis.

The DJ - who has been dating the 'Mean Girls' star since early this year - is allegedly forcing Lindsay to continue in the lesbian relationship, according to the 'Girls Gone Wild' entrepreneur.

After learning of Joe's claims, Samantha retorted: "I think Joe Francis is one of the more disgusting human beings in the world because of what he does.  He should find something else to talk about."

This is not the first time Joe and Samantha have come to blows.

Earlier this month, Samantha claimed Joe had ignored her at a party for the MTV Video Music Awards (VMA), adding: "He said hello to Lindsay and looked over at me as if I wasn't a human being. He's got no manners."

Lindsay is growing tired of the arguments between the pair.

She wrote on her blog: "Joe Francis has no place in saying anything about Samantha, especially after all the s**t he has done."
