Khloe Kardashian Slams Former Stepmom Over Real-Father Rumors: ‘Do Not Talk About My Dad’

Word to the wise: Do not cross Khloé Kardashian. In a new preview for the Wednesday, March 9, episode of Kocktails With Khloé, the reality star takes aim at one of her late father’s former spouses who made claims that Robert Kardashian was not Khloé’s real dad.

“I think the thing that most became overwhelming was when, like, the stuff happened with one of my dad’s wives,” the Strong Looks Better Naked author, 31, says during a discussion about the dark side of fame. “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.”

While she fails to mention a name, it’s most likely that Khloé is talking about Ellen Pierson, Robert’s ex-wife who sold excerpts from his private diary to a tabloid in 2013 — a decade after the lawyer’s 2003 death at age 59 from esophageal cancer. In an accompanying interview, Pierson said that Robert openly admitted to her that he wasn’t Khloé’s biological parent.

“I was like, ‘Listen, you can talk about me and my sisters all you f–king want,’” the talk-show host adds in the clip. “Do not talk about my dad.… He’s not here!”

On February 22, Khloé took to Instagram to pay tribute to Robert on what would have been his 72nd birthday. “To the best man I've ever known, happy birthday daddy,” she captioned an adorable throwback pic of her younger self with her father. “I miss you! I miss you! I miss you! Man… I wish we had more pictures together.”

Robert’s name has been back in the news since the premiere of FX’s new miniseries, American Crime Story: The People v. O.J. Simpson, in which David Schwimmer portrays him.
