Lindsay Lohan thinks whoever leaked her list of famous lovers was ''cruel''.

The 'Mean Girls' star was forced to defend herself when a list of her famous sexual partners, including Colin Farrell, Justin Timberlake, The Wanted singer Max George and Coldplay's Guy Berryman, was made public earlier this year.

The 28-year-old actress - who insists she wrote down the men's names as part of an exercise in rehab before accidentally leaving it in a bar - says she was left ''really hurt'' by the betrayal.

She told The Sun newspaper: ''It's a really personal thing that you do with one other person and no one ever sees it.

''So, that really hurt.''

''I wrote it when I was at the Betty Ford (rehab) clinic. Writing that was one of my steps in AA (Alcoholics Anonymous).

''The anonymity of that should never have been leaked - someone stole that and put it out. And that's a really cruel thing to do.''

The 'Parent Trap' star - who is in the process of writing her autobiography - says she ''would never'' include details about her sex life in the work.

She said: ''I think it will be more like the 'Harry Potter' series. I won't be able to fit it all in one book.''
