There has always been rumours that OJ Simpson might be Khloe Kardashian's father but was adopted by Robert Kardashian who Kris Jenner was married to that period.

He has agreed to a paternity test to see if Khloe Kardashian is his daughter - but only if she goes to see him in person.Daily Mail Online has learned that Simpson wants Khloe to 'show him a little respect' and make a personal appearance at Lovelock Correctional Center in Nevada.

He will agree to have a swab to his mouth which will provide the DNA sample needed to clear up the paternity mystery over the reality star.

Jeffrey Felix, a former Lovelock prison guard who wrote a book about Simpson, claims that the jail authorities have even given their permission for the test to go ahead.
