(NEWSER– It's just what you wanted for Christmas: Lindsay Lohan is writing a tell-all. Sources tell TMZ she's already met with a big literary agency and has even received a few six-figure offers, so there's pretty much no escaping it.

The book will be based on journal entries she wrote as part of her rehab therapy, and will discuss her arrests, drug problems, career, and of course, her ...interesting family.

Not surprisingly, sources say the book doesn't yet have what TMZ calls "a clear focus." Even better: Her meeting with the agency was filmed as part of a docu-series to be aired on the Oprah Winfrey Network.
