All For Show! Kris Jenner's Sister Insists Bruce 'Walked Out On Her' & 'He's Not Coming Back,' Despite Recent Appearances Together

Reality TV isn’t so real, especially when it comes to Kris and Bruce Jenner. After separating last October, the most infamous on-camera couple has been spotted vacationing together in Thailand, holding hands in public, and sharing anniversary love notes. But now, Kris’ sister Karen Houghton told RadarOnline.com exclusively that it’s yet another case of Kardashian fakery -- because they are never ever getting back together!

“Bruce left Kris,” Houghton told RadarOnline.com in an exclusive interview. “He walked out on her, and I think he’s not coming back.”

And, according to Houghton, it was not Kris’ decision.

“I think she’s got issues right now because Bruce left her,” Houghton claimed. “He couldn’t take the yelling anymore and stuff.”

As RadarOnline.com previously reported, Kris and her younger sis haven’t had the closest of sibling relationships, but that hasn’t stopped Houghton from expressing why she thinks Kris’s marriage crumbled after 22 years – and why she thinks it’s for the best.

Now that they’ve separated, Kris and Bruce are “not on each other’s backs all the time and yelling at each other telling each other what to do,” Houghton explained.

All told, it’s a very different picture than what Kris has tried to portray in the media. On Monday – her 23rd wedding anniversary with Bruce – she posted a note that called him “one of the most amazing men I know” on Instagram, adding “I love you.”

Before Kris and Bruce’s recent attempt at launching a public reconciliation, the 58-year-old cougar had been linked to 31-year-old former Bachelor star Ben Flajnik and, like her daughter Kim, there were reports of a sex tape.

Still, Kris isn’t the playing the field just yet, Houghton insisted.

“Kris is alone, she’s not dating. She’s not the type to run around,” she said.

But Jenner has insisted that if she were, Houghton, 55, would be the last to know. She told RadarOnline.com exclusively last year that the two have been estranged, and for good reason.

“Unfortunately, my sister has been dealing with demons for years,” Jenner told RadarOnline.com. “I am not in touch with her. But I wish her the very best.”

Houghton, who lives far from Hollywood, in the San Diego area, is content with the distance.

“I think she’s from another planet,” Houghton, who calls the hustle and bustle of Tinseltown Kris’ own “weird world.”

Among the most recent oddities are rampant rumors that 64-year-old Bruce plans to undergo a sex change, and Houghton couldn’t resist weighing in on those as well.

“I love him to death, but is he okay?” she asked. “If I was Kris, I would be so embarrassed. If your husband left you and if you believe the reports that he wants to be a woman, I would be so embarrassed!”
