Michael Lohan is writing his memoir.

The father of troubled actress Lindsay Lohan has signed a deal with South Florida PR firm TransMedia Group and its founder Tom Madden to co-write the book, which will focus on his ''rise from drug addiction and imprisonment to a Bible-quoting minister, drug interventionist and successful businessman''.

Mr. Madden said the tome, 'I'm Not Your Daddy Dearest...If I Can Turn My Life Around, So Can You', will show a different side to Michael than has been previously portrayed.

He explained: ''So much of the press Lohan receives misfires as it characterises him as a 'drug abusing, felonious stock trader', as opposed to the decent, honourable guy I know.

''Readers of his tell-all memoir will meet a very different Michael Lohan, the real one.''

The autobiography is also set to focus on Michael's troubled relationship with Lindsay.

Mr. Madden added: ''Our publicity will show Lohan cares about his daughter, how he battled his own addiction and today helps others stay clean.

''Often he pleads in interviews for a judge to order his falling star daughter into a six month drugs/detox programme which he believes she desperately needs.''
