Kris Jenner's sister is once again spilling details into the matriarch's rocky marriage to Bruce Jenner. Kris and Bruce announced they were separated after months of speculation that the marriage was over. Karen Houghton first told Star magazine that Kris and Bruce were already separated even before the couple made the announcement.

Now she is opening up about their relationship hinting that Kris might have cheated on the former Olympian.

"Kris has admitted to cheating," Houghton said but not referring to when the cheating took place. "It's so funny because I could never see a guy cheating on her. She's so powerful."

Houghton said she believes Bruce, who she called the "nicest guy," never cheated on Kris and never would if they do end up staying together. The sister, who the family calls "Crazy Aunty K," told the magazine that she is sure in the event of a divorce Kris would move on a whole lot faster than her husband.

"Bruce will find someone else," she said. "But I guarantee you, Kris will find someone in two days, I promise."

As far as what led to the separation, Houghton believes the momager had too much going on in her life and couldn't handle it all. She said the allegations surrounding Khloe Kardashian and Lamar Odom "devastated her."

"The stress was beyond what any mother could take," she said. "And then Kanye had moved in with Kim so the house was kind of crazy and I think there was too much on her plate. And then Bruce moved out... I don't think Kris knew how to handle it. I think she tried her very best but she just couldn't do it all."

Even though Houghton keeps dropping bombshells about her sister she told Star that she hopes the marriage will work out because she honestly feels like Kris and Bruce make "an amazing couple."
