Kris Jenner's sister Karen Houghton

Kris Jenner's sister Karen Houghton, Kris Jenner has hit back at her sister Karen Houghton, who claimed that the Kardashian matriarch cheated on estranged husband Bruce and reckons she would find another man “in two days” following the split.

America's reality TV power-couple, Kris and Bruce Jenner, confirmed the news last week that they have split up after 22 years of marriage.

“Unfortunately, my sister has been dealing with demons for years,” Jenner told RadarOnline.

The 57-year-old, who is mother to Kourtney, Kim, Khloe and Rob Kardashian and her children with Bruce, Kendall and Kylie, revealed she’s not in touch with her sister.

She added, “I am not in touch with her. But I wish her the very best.”Sources say the two sisters have not seen each other for nearly a year. An insider explained to Radar: “The reality is that Karen and Kris have not had a discussion about Kris’ private life for 28 years.”

“She has no knowledge of Kris’ family life or her husband,” the source added. “Except what she sees on the show. And she has used this to create a fanciful tale of what is going on inside the family.”

“Karen has a tendency to be angry and jealous and perhaps this was her motivation to go on the media tour,” the insider claimed.

“Kris feels horrible that her sister felt the need to talk to the media,” the source continued. “It’s disappointing that she has sold her out.”

“The irony is that Kris has always been there to help Karen financially. It shows just how crazy this situation is. Kris even sent her a brand-new Mercedes, then Karen goes and blabs to the media.”
