Lohan and Ronson have been close friends for several years and are now said to be in a relationship.

And Ronson is reportedly set to reveal intimate details of her life in a new memoir.

A source tells UK Eonline, ""She's certainly telling friends she's planning to write a book. It's supposed to be about her, allegedly. But come on, you know

Lindsay will be all over that book. She's the only one people want to read about.""

And the rumors have infuriated Lohan's father, who claims the DJ is just using his daughter to get her own slice of fame.

He says, ""I've shut up about this long enough. She's using my daughter. People never even knew who Samantha Ronson was until she met Lindsay. She was

just some Los Angeles DJ. And now she's writing a book? I am at (my) wit's end with this stuff. This is not in Lindsay Lohan's best interest. Let's just say I hope Lindsay starts opening her eyes and realizes who the people using her are.""
