OJ SIMPSON reveals how he would hypothetically have killed his girlfriend and her lover in a new TV documentary.

OJ: The Last Confession comes after The Juice's book publisher and a close pal both claimed he confessed to murdering Nicole Brown and Ron Goldman in 1994.

5 Could this be the moment OJ Simpson accidentally confessed to killing his ex-wife?

In The Fox special, OJ will reportedly say he had a violent clash with tragic Nicole over her drug use and her relationship with friend Faye Resnick, who OJ labels "a hooker", claims the Daily Mail.

In his "imagined" version of events, OJ says he confronted Nicole at her home with an accomplice he calls Charlie.

The ex-NFL star then claims, in his version, that she fell over during the row prompting her alleged lover Ron Goldman to start a fight using karate.

Simpson says he blacked out and fled with "Charlie" after waking up covered in blood.

OJ: The Last Confession will air Sunday at 8pm on US television.

Meanwhile, Judith Regan, who was looking to publish OJ's controversial book "If I Did It" - another hypothetical account of how he would have murdered his wife - claims the star confessed via his lawyer 12-years ago.

Judith claimed in an un-aired Fox interview at the time, that she received a call from OJ's lawyer who said he was ready to admit it.

In a clip obtained by TMZ, she told the show: "The only condition he had was he didn't want to call the book I Did It.

"He wanted to put an 'If' in front of it so he had deniability with his children. He couldn't face his children and couldn't tell them that he'd done it.

"That was the way it was portrayed to me."

Two years ago, in a documentary OJ: Made In America, the shamed-footballer's pal Mike Gilbert says he confessed while they drank beers and smoked pot.

Gilbert recalled: "I just asked him: 'What happened June 12th?'
