The Twitter war between Kim and Khloe Kardashian and the wife of their late father Robert Kardashian is getting uglier.

The Kardashian sisters called their stepmother Ellen "delusional" and a "black widow" on Twitter, according to Radar Online, after Ellen accused the sisters of lying about her relationship with her late husband.

It all started when Ellen Kardashian sold diaries to US Weekly that she said were written by Robert Kardashian, that described Kris Jenner abusing and neglecting her young daughters.  "Kris was kicking and beating her and said she was going to kill [Kim]!" one entry reads, in an excerpt provided by In Touch. "Kim was hysterical."

The Kardashian sisters lashed out at their stepmother on Twitter and said the diaries were fake: "So my dad's ex is selling ridiculous stories again to tabloids!" Kim tweeted last week, "Do not believe it! Sad when people need $ and get desperate."

Ellen Kardashian insists the diaries are real, telling In Touch, "These are authentic handwritten journals I have shared, that my late husband Robert Kardashian so carefully wrote...at a most trying and touching time of his life."

Then on Friday, she added that the girls had misrepresented her relationship with her late husband. "I was with Robert for almost five years total," she said, according to Radar Online. "We didn't just run out and get married...We had a beautiful wedding with the girls and all of his family at our home. It's sad they choose to lie when they know their father was so happy on that wonderful day."

But Kim and Khloe held their ground on Twitter, Khloe tweeting, "10yrs after my father's passing&now that she has filed for bankruptcy...NOW she sells FALSE stories. Hope that money buys you water in hell," according to Radar Online
