Who is Kris Jenner's sister?

You know all the names from Keeping Up With The Kardashians. You probably know more about Kris Jenner and her famous brood than you care to admit. But there's another famous "K" you might not know existed — Kris' younger sister, Karen Houghton. A former stewardess turned part-time nurse, Houghton is known as "Crazy Auntie K" to her reality show famous nieces and nephew, but she reportedly fell out with her media mogul sister for as of yet unconfirmed reasons.

However, we can confirm that the estranged relationship has taken a turn for the worst in recent years, due to Houghton's penchant for spilling to the media at every opportunity. From her calling Kris and Caitlyn's divorce, and her disdain for getting yet another Kim wedding invitation in the mail, to her face-lift that was broadcast on television for the world to see, here's everything we know about Kris Jenner's sister. 

She called the Kris and Bruce split

After 22 years of marriage, Kris and Bruce Jenner split in late 2013. However, a few months later, the queen of reality television and the former Olympian were (per Radar Online) "spotted vacationing together in Thailand, holding hands in public, and sharing anniversary love notes," leading celebrity gossip rags to speculate a possible reconciliation was on the horizon. Houghton wanted everyone to know that all the camera-friendly PDA was all for show.

"Bruce left [Kris]," she told Radar in an exclusive interview. "He walked out on her, and I think he's not coming back." Saying Kris was "from another planet," Houghton claimed Bruce "couldn't take the yelling anymore and stuff" and suggested the rumors of Kris dating Ben Flajnik were false. "Kris is alone," Houghton added. "She's not dating. She's not the type to run around." 

As for the reports that Bruce wanted to undergo a sex change operation to transition from male to female, Houghton's take wasn't as evolved or insightful. "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!"

Houghton shot an impressive 50 percent on the details of their split, because as we all know, Kris and Bruce Jenner eventually divorced. But Kris doesn't seem to be embarrassed that Bruce is now Caitlyn. 

Kris tries bribes to keep her quiet

Kris readily admitted to cheating on her late ex-husband, Robert Kardashian, and sleeping with soccer player Todd Waterman at the beginning of her relationship with Bruce, but Karen Houghton had something else to share with In Touch Weekly: "I've heard she flirts with Scott [Disick, Kourtney's children's father] and Lamar [Odom, Khloé's ex-husband] when she's drunk." TMI, Karen. A source claims Houghton "knows where all the bodies are buried," and each time she talks to the press, it's "Kris' worst nightmare." That appears to be a pretty lucrative job.

"She sent down a Mercedes for Valentine's Day. I went out front, and there was a big bow on it,"  Houghton revealed. "She also furnished my whole house [in 2009]. A truck came down with $50,000 worth of furniture." Keeping Houghton away from the cameras while lavishing her with gifts doesn't seem to be a workable strategy for the celebrity momager. Houghton's response to a new car and furniture? She called Kris "crazy and controlling."

She claims Kris is a deadbeat daughter

Kris Jenner has a reported net worth of $60 million, but according to Karen Houghton, none of that is trickling down to their elderly mother, Mary Jo Campbell. In yet another interview with Radar Online, Houghton says Kris could "do a lot more for her family," and claims Kris could give their mother "anything she wanted" due to her substantial wealth. Houghton has grown frustrated with her estranged sister's alleged hypocrisy. She added, "[But] when you express a loving family and family values and a close family and my mom wants to live in La Jolla, buy her a condo, Kris! I don't understand her. I never will. It's just her personality."

She didn't stop there. Houghton says her famous sister's life is just going "after the money" and that she doesn't help the rest of her family "because they aren't famous." She added, "She's a huge celebrity and now she has changed. I'm not saying good or bad, but I've seen what it can do to Kris... ever since she moved to L.A." Houghton had some more choice words for the City of Angels and a parting shot for her niece. "It's too greedy. I hate L.A.," she said. "Even if you bought me an $8 million mansion like Kim and Kanye, I wouldn't live there."

She blames Kylie's behavior on Caitlyn

In 2015, Kylie Jenner was no longer the quiet sister. She had a completely new look and her headline-making antics led the media to question if she was headed towards an Amanda Bynes-level breakdown. Fortunately, that didn't happen. But at the time, Houghton blamed the younger Jenner's erratic behavior on her father's transition to a woman: "I call Kylie my wild child. Is she wild because of Caitlyn? Yes."

While we don't know if that claim is true, the relationship between Kylie and Caitlyn has been strained since the divorce and transition. In an episode of the eight-part documentary series, I Am Cait, the former gold medal winner revealed she wasn't invited to Kylie's high school graduation — placing the blam solely on her ex-wife. "It wasn't me making that decision. It was you making that decision. I was so disappointed in everybody," a tearful Caitlyn told Kris (per Female First). "For 15 years of my life, I carpooled the kids every day. Some days, I would spend three or four hours in the car. [It's] a slap in the face when you don't even get invited to their graduation."

Kris strikes back

In an M. Night Shyamalan-esque plot twist you probably saw coming, Kris had enough of her sister running to the press, so she decided to run to the media herself to set the record straight. "Unfortunately, my sister has been dealing with demons for years," she told Radar Online in statement. Wow, she even went to Houghton's favorite source. That's some quality trolling. 

An insider picked up the rest of the heavy lifting, stating that Houghton has no knowledge of Kris' family life or her relationship with Caitlyn except for "what she sees on the show." The source added, "Karen has a tendency to be angry and jealous and perhaps this was her motivation to go on the media tour."

Houghton's constant gabbing to the press has driven a chasm between the already distant sisters and Kris feels her sister has "sold her out." The source concluded, "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." Maybe send another Mercedes? 

She passed on Kim and Kanye's wedding

Kim Kardashian and Kanye West had their hearts set on exchanging vows in the Palace of Versailles, but got denied. They settled for their guests flying into Paris and receiving a guided tour of the Palais de Versailles, then traveling to Italy to witness the ceremony at the Forti d Belvedere in Florence. Sounds like a fun time, right? Maybe to everyone except Karen Houghton. "I've been to Kim's weddings, two of them, and I've been to Paris," she told Daily Mail. Dude. We wonder if Kylie sells any cream for burns. 

Apparently Kim called her aunt and offered up a plane ticket, but Houghton was more concerned with the wildfires raging near her home in San Diego County. She said, "If your house was going to burn down would you go to Paris? Screw it — I've been to two weddings of Kim! But I'm really happy for her and I do have a present for her."

On the bright side, she believes this marriage will last longer than Kim's second try with NBA player Kris Humphries in 2011: "I think this one's going to work. I think it's going to be more than 72 days!" She continued, "I think it's going to work, I mean look at Nori, how adorable. I just love them and hope they're happy." No word on whether or not she'll attend a fourth.

She had a face-lift

If there's one thing Houghton has in common with the rest of her famous relatives, it's extensive plastic surgery that completely changes the structure of your face. Hopefully, they let her use their Groupon for the face-lift she received in late 2016. The procedure? An auralyft, the most expensive face-lift in the world. Performed by Dr. Ben Talei of the Beverly Hills Center and documented by Inside Edition, Houghton went under the knife for the five-hour surgery with not-so-surprising results. 

After three weeks wrapped in thick bandages to reduce swelling, Houghton emerged with a different yet familiar face. "I look like my beautiful sister Kris and I never thought I would," she told the cameras. Although she claimed she "wanted to do it for me," Houghton admitted she wanted a new look to, in essence, keep up with the Kardashians. "And of course the Kardashians," she explained. "Everyone wants to look beautiful."

Shout out to Houghton for inviting cameras to film her plastic surgery. A plastic surgeon's office might be the only place in the world where any Kardashian or Jenner can have a private conversation. 

Her daughter is a model

If you thought the Kardashian/Jenner clan was running low on wannabe models, meet Houghton's daughter — Natalie Zettel. Graduating high school in 2017, the 18-year-old now has set her sights on joining a branch the family business — posing on Instagram.

But don't expect her to join the E! family anytime soon, because in a 2013 interview with Star, the aspiring model admits she didn't inherit the gene that makes her put her entire life on television. Saying she'd be down to appear on Keeping Up With The Kardashians on occasion, the prospect of having a show of her own has zero appeal. She says, "I feel I would just be like 'get out of my face!'"

She calls her famous kin her "blood" and says that she's "stuck with them," but she tempers the expectations of anyone who might think that's amazing. She explains, "People are like, 'Oh my Gosh! You're cousins with the Kardashian family? Is that weird?' And I say, 'No.' They're nothing special. In my eyes, they're just my family." No wonder you've probably never heard of her.

Her final thoughts? "My mom is great and I love her, and I love my Kardashian family—and that is that."

Kris sees her as a threat

There would be nothing more on brand than Kris Jenner secretly terrified that Natalie will one day outshine her famous daughters, so it shouldn't come as a surprise that might be the case. Allegedly worried that Natalie might "steal the spotlight" from Kylie and Kendall, the media mogul (per Inquisitr) is reportedly "concerned about the increasing amount of attention" that her niece is getting on social media.

At the time of this writing, Natalie has 39,100 followers on Instagram. While that's a far cry from Kendall's 92 million and Kylie's 110 million, Natalie earned those followers "without any help from her famous family." And according to Radar Online, those 39,100 followers don't include any of her TV star cousins. One fan wrote on Instagram, "That's so rude of Kim, Kylie, etc. that they are not even following her."

Kylie removed her lip fillers recently so this may be a preemptive strike.
