Simpson was represented by Khloe's father Robert during the 1994 murder trial over the death of his wife Nicole Simpson Brown. The rumor has never been substantiated.
In video obtained by TMZ, a photographer asked Simpson, 70, if congratulations were in order in reference to Kardashian's pregnancy.
"But I don't know for me". "I don't think for me".
When asked about the reports, Simpson said, "I would be proud if I had anything to do with it, but I don't".
Fans of KUWTK will remember that Khlo-money even had doubts at one point herself over her parents, forcing mama Kris Jenner to step in and shut down the rumours with a DNA test. I'm so hurt she needs to deal with this all.
Throughout the years, rumors have circulated that Kris may have had an affair with Simpson during that time. Soon after the rumors rocked Hollywood, Khloe, Kim Kardashian, 36, and Kris Jenner, 62, all took to Twitter to laugh off rumors that Simpson was Khloe's real father.
'She wanted to come out, like, 10 years later after my dad passed away and said that I'm not his daughter and that he confided in her and blah-say-blah.
But Simpson has now denied the rumour.
'I was like, "Listen, you can talk about me and my sisters all you f***ing want", she said, '"Do not talk about my dad ..."
Robert's second and third wives have also claimed that the late-Kardashian told them both that Khloe was not his child.
He was released in October 2017 after serving nine years for armed robbery and kidnapping.
