Uh-oh! Is Samantha Ronson planning to tell-all about her steamy same-sex romance with actress Lindsay Lohan? At least one spy close to the lesbian DJ says so!

“Well, she’s certainly telling friends she’s planning to write a book,” a source close to the turntable star whispers. “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.”

Lindsay’s always chatty pop, the recently engaged Michael Lohan, says he’s also been told that Samantha is writing a book, and, as usual, had a mouthful for anyone who would listen.

“I’ve shut up about this long enough,” Michael said. “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.”
