O.J. admitted he killed Nicole

At least that's what author Mike Gilbert would like us to believe in his new book, How I Helped O.J. Get Away With Murder: The Shocking Inside Story of Violence, Loyalty, Regret and Remorse. I don't think the title of the book is long enough, but oh well.

Supposedly... a groggy Simpson, high on marijuana, confessed to killing his ex-wife after he was acquitted.

Gilbert also claims he helped his former friend wiggle out of the murder charges by suggesting how to bloat his hands so they wouldn't fit the notorious bloody gloves.

You mean, it's possible that O.J. lied? No way!

Simpson said he went to his ex-wife's condominium, but did not bring a knife with him. Simpson told him Nicole Brown Simpson had one in her hand when she opened the door.

In a soft mumble, Simpson told him: "If she hadn't opened that door with a knife in her hand ... she'd still be alive."

"Nothing more needed to be said," Gilbert writes. "O.J. had confessed to me. There's no doubt in my mind."

And here's the biggest shocker... O.J.'s lawyer says that what Gilbert claims is untrue. I didn't see that coming at all.
