In the wake of the separation between Kris and Bruce Jenner there have been several reports regarding the pairs deteriorating relationship, but Kris' sister is alleging infidelity.
During an interview with Star magazine, Kris' sister Karen Houghton said that Kris admitted to being unfaithful.
"Kris has admitted to cheating," Karen explained in the interview. "It's so funny because I could never see a guy cheating on her. She's so powerful."
Her sister also insists that Kris' drive for money and success came at the expense of her marriage and family.
"My sister is a person who likes to stay really busy, focused, in control, done, done, ABC, you know," she continued. "And even a little bit anal. But I think that's because when you have situations inside of you that aren't filling your complete happiness, there's a hole in you. And I think right now, Kris has that hole in her because of what's going on with the family right now."
Some even ebelieve Kris wants to use the couple's marital problems in order to draw attention back to her show and increase ratings.
"Kris has no desire to get back together with Bruce, but she wants to film a 'reunion' of them attempting to work things out, which would all be designed for the show," a source told Radar Online.
Bruce and Kris have been subject to divorce reports for several months and have two children together, Kendall and Kylie, in addition to other children from previous relationships. However, neither publicly admitted that either cheated during their marriage.
In a statement Kris, 57, and Bruce, 63, revealed that their family is their number one priority.
"We are living separately and we are much happier this way but we will always have much love and respect for each other," the couple told E! News. "Even though we are separated, we will always remain best friends and, as always, our family will remain our no. 1 priority," they added.
