O.J. Simpson responds to claim he’s Khloe Kardashian’s biological father

O.J. Simpson has acknowledged for the first time the rumours that he is Khloe Kardashian’s biological father.

There have been reports going back years that Khloe was conceived after a one-night stand between the former football star and Khloe’s mum Kris Jenner, despite Simpson being married to Nicole Brown Simpson and Jenner being married to Robert Kardashian at the time.

When asked by TMZ if he wanted to congratulate Khloe on her recent pregnancy news, Simpson replied “Well, for Bob [Robert Kardashian], God bless his soul, yeah. I don’t know for me. I don’t think for me I have nothing to do with it.”

“I would be proud ... but trust me, I had nothing to do with it.”

The two couples were close in the years before Nicole’s murder, with Kardashian going on to defend Simpson when he was on trial for her death in 1995, in which he was found not guilty.

In 2013 Simpson’s ex-manager Norman Pardo told InTouch Weekly he believed O.J. was Khloe’s real dad.

“It’s all going to come out sooner or later,” Pardo said

“They all [O.J., Nicole, Kris, Robert] took their vacations together. There was a lot of partying going on back then …. Kris cheated on Robert — she was known for having a good time,” he said.

Khloe has long denied she is Simpson’s offspring — even amid a National Enquirerreport last year that Simpson had changed his will to include her.

Last year she furiously hit back after being bombarded by trolls on social media about her “dad” being released from prison after O.J. was granted parole.

Khloe responded to the wave of abuse dominating her Instagram comments by branding the trolls “a**holes” and “haters”.

Kris Jenner has also denied the allegations.

She slammed speculation about her daughter’s parentage as “c**p” in 2012 on Good Morning America.

“It just gets weirder and weirder: I have never heard such c**p in my life. I mean, I was there! I gave birth, I know who the dad was.”
