OJ Simpson�s autobiographical book �If I Did It� was apparently penned by a ghost-writer, and when we see ghost we don�t mean his ex-wife Nicole.

"O.J. told me [ReganBooks publisher] Judith Regan approached him and said to him, 'Do you mind if we write a book and put your name on it?' He said, 'I don't care. You can write anything you want, as long as you pay me,'" said promoter Norm Pardo to Page Six.

Pardo continued "O.J. would laugh, 'Can you believe they'd pay me to say I wrote something I didn't actually write?' A ghostwriter largely based the book on court transcripts from Simpson's trial."

Beware OJ, your ghosts will come back to haunt you...
