LiLo to pen tell-all-book

London – Lindsay Lohan is reportedly writing a tell-all book that details her time in rehab.

The 27-year-old actress met literary agency Waxman Leavall in New York last Thursday to discuss her upcoming project, the Mirror reported.

Although the book is still in its early stages, the troubled star began it as a series of journal entries while she was recuperating in rehab.

The tell-all-book is expected to see Lohan open up about becoming a child star, allegations of drug use, her relationships – including her same sex fling with DJ Samantha Ronson , legal troubles and rehab stints.
