is lashing out at her often-estranged dad, Michael, who has been openly critical of her relationship with Samantha Ronson.
"He has become a public embarrassment and a bully – to my family, my co-workers, my friends and a girl that means the world to me," she writes on her MySpace Celebrity blog
, listing her current mood as "betrayed."
Lingering tensions came to a head this week, when Michael Lohan dissed Ronson in the media. "Samantha is using my daughter," he told E! News
, as reports swirled that Ronson was planning a tell-all memoir. "People never even knew who Samantha Ronson was until she met Lindsay. She was just some Los Angeles deejay. And now she's writing a book?"
But Lindsay insists her dad "has no idea what is going on in my life." She adds, "Samantha has not, and would never, sell me out.”
Ronson has also joined in the family feud, posting her own response
"I am not the reason that he has no contact with his daughter – he is," she writes. The deejay – who says she has no plans to write a memoir – also claims Michael is "so desperate for attention that he goes to the media whenever possible."
