Kris Jenner's scathing Twitter words didn't just rub Perez Hilton the wrong way.
When the famous momager publicly told the blogger that "no one" asked her to comment on ex-husband Bruce Jenner's explosive TV revelation that he's transitioning into a woman, she irked Diane Sawyer in the process, Radaronline.com has learned exclusively.
The award-winning journalist, who scored the historic sit-down with the Olympic hero on Friday night, is "furious" at Kris for claiming that ABC failed to reach out to her for a response.
"Kris was sent an early copy of the interview and had more than enough time to issue a comment," a network source tells Radar.
"Diane is angry that Kris attempted to discredit her. She's a seasoned journalist and for a reality star to infer she's lying is insulting."
On Friday night, Hilton called out Kris for not providing ABC with a statement, unlike Bruce's other supportive exes, Linda Thompson and Chrystie Scott.
The angry Kardashian matriarch blasted the blogger, even spewing the f-word.
Not only did Kris lie, she took attention away from Bruce's big night, the source explains.
"Bruce's story was supposed to be all about him making a difference, and Kris cast a shadow over the message. It's uncalled for."
After the online uproar, Kris later wrote a more supportive message to her fans, referring to her ex as a "hero."
But the legendary news anchor isn't satisfied.
"Now she's started a war," the source says, "and Diane wants Kris to issue an apology."
