Book club alert!

Lindsay Lohan's girlfriend, Samantha Ronson is rumored to be writing a book. Sources close to the DJ say that Sam is claiming the book is about her life -- but that nobody believes that for a second.

"Well, she's certainly telling friends she's planning to write a book," said a source close to the Sam and LiLo said. "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."

Very true, smart guy.

And just in case you haven't had enough of Michael Lohan's big mouth, here's what he thinks about the possibility of his daughter's constant companion's literary aspirations.

"I've shut up about this long enough," Michael ranted. "She's using my daughter. People never even knew who Samantha Ronson was until she met Lindsay. She was just some L.A. DJ. And now she's writing a book? I am at wit's end with this stuff. This is not in Lindsay's best interest."

Yes, nobody, other than him, is allowed to use Lindsay to further their celebrity, you hear?
