Kris and Bruce Jenner were married for 22 years -- an eternity by Hollywood standards. The couple confirmed that it had separated last week. Now, the reality star's little sister is airing loads upon loads of family dirty laundry.

Kris previously revealed that she had several affairs while married to the late Robert Kardashian, father of four of her children -- Kourtney, Kim, Khloe and Rob. Or so we think.

Kris' sister Karen Houghton has done some interviews revealing that the Kardashian matriarch has a rich history of cheating and once again cast doubt on the paternity of Kris' daughter Khloe.

Houghton called her brother-in-law Bruce "the nicest guy" and claimed that she does not believe "has ever cheated on Kris…and I don't think he ever will, if they stay together."

“Kris has admitted to cheating,” Karen revealed in a bombshell interview. Again, that's not a shock, as Jenner admitted to it in her memoir.

Houghton continued, "It’s so funny because I could never see a guy cheating on her. She’s so powerful."

Karen believes that if the marriage does end in divorce, Bruce will find another love. But not as quickly as his wife. "But I guarantee you, Kris will find someone in two days. I promise," Karen said.

Karen revealed the status of her own relationship with Kris, saying, "I wish she could’ve spent a little more time with me in the past few years. But I understand that she’s had a business and she had to be busy."

That has us wondering why she chose to pull back the curtain and reveal all. If their relationship is not acrimonious, why threaten to end it by opening her mouth to the media? Hmm...

She further said, "My sister is a person who likes to stay really busy, focused, in control, done, done, ABC, you know. 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."

Despite going public with family business, which would seem to cause a rift between the sisters, Karen was repeatedly complimentary about Kris, citing Khloe's seemingly crumbling marriage to NBA star Lamar Odom and daughter Kim moving in with baby daddy Kanye West as instances which strained Kris' life and marriage.

"...The stress was beyond what any mother could take," Houghton said, "And then, you know, 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, she’s amazing, but I just think she couldn’t do it all."

Sounds like Karen insults Kris with one hand and compliments her with the other.

Regarding Khloe, it's long been rumored by multiple sources, including Robert Kardashian's widow, that he was not her real father. She doesn't look like sisters Kim and Kourtney and is much taller, which lead to suspicion that someone else was her dad. Perhaps Kris' infidelity caught up with her?

In another interview, Houghton said she believes the truth about Khloe's paternity will be revealed soon. She did not confirm or deny the rumor that Kris' hair stylist Alex Roldan is Khloe's dad and those photos certainly demonstrate a physical similarity.

What a mess.
