Tabloids flew off of supermarket shelves when rumors that Kris Jenner had beaten her children made headlines earlier this year, thanks to the late Robert Kardashian’s ex-wife, Ellen Pearson Kardashian. But inside the Kardashian clan things got understandably messy, and on last night’s episode of Keeping Up With The Kardashians, Kris started to lose it!

“Dad’s ex said that mom used to beat me and kick me,” Kim tells her horrified sisters on the show. Even though they clearly give Ellen no credibility whatsoever, the girls are concerned about their mom. And their concern is justified, because when they get to Kris’ house, she’s on the verge of a full-blown anxiety attack.

“I just am trying to wrap my head around how someone gets away with...” Kris trailed off.

“I would never claim to be the perfect parent, because I don’t think anybody has an instruction book on how to raise their kids,” Kris told the KUWTK cameras. “But this woman is really crossing a line accusing me of doing things that I would never dream about doing.”

Kris wants the family to just drop it, but Kim won’t have it. “We’re not going to let this woman get away with something this crazy.”

Kim has a plan, which can only mean one thing: Jake is back! Our favorite goatee-ed PI from Kourtney & Kim Take Miami starts digging into Ellen’s background, and he doesn’t disappoint. Not only has Ellen been married five times, she’s also filed for bankruptcy more than once.

Now that they feel sure they can prove Ellen is just making up stories for the money, the girls bring a lawyer to Kris’ house, to look into what can be done about her salacious claims.

As they discuss defamation, libel, and privacy issues, Kris loses it. “I just can’t.” she says, as she buries her face in her hands and starts to cry.

But she gets through it all, including the long, crazy process of serving Ellen her court documents, because her family has her back.

You know what they say: The family that sues crazy exes together, stays together!
