Kim Kardashian has an ugly temper and a vile tongue that the public apparently rarely sees because of careful editing of their reality shows, according to a source close to her ex-husband Kris Humphries.

Humphries, a star NBA player with the New Jersey Nets, reportedly was stunned with the way Kim talked to his mother and family as well as her sisters and her own mother, Kris Jenner, a source told gossip site radaronline.

Humprhies, who is in the midst of his divorce from his reality show wife, has said he can’t wait until the truth comes out about Kim and her shows. But so far the big star has been silent himself. In his only interview, he declined to talk about the marriage.

“Kris just couldn’t believe that Kim, 31, would speak to her mom with such disrespect, often telling her she had no idea what she was doing, as pertaining to Kris’ management of her career,” the source said.

Did Kim Kardashian Fake Dubai Car Ride?

Fans and the public got a taste of Kim’s vitriolic personality on an episode of “Kourtney & Kim Take New York.” She called sister Khloe Kardashian an “ugly little troll.” That’s after Khloe tried to wake up Kim before she was ready to get up. The comment had to be especially hurtful. Khloe is very sensitivity about her looks and her height compared with Kim and sister Kourtney Kardashian.

“Kris would never even joke with his parents, nor his sister, Kaela that way. He just wasn’t raised that way,” the source claim. Yet on the show, Humphries has been portrayed as oafish and insulting to Kim and her friends. It’s unknown how much of his behavior, if any, was scripted in advance to create drama on the show.

“Kris tried to approach the subject gingerly with Kim, saying there were other ways to communicate her frustration and anger, rather than using such ugly language, Kim responded by telling him that it was none of his business,” the source claimed.

Is Kim Kardashian Radioactive as Marriage Material?

The situation also raises another question: Was Kim trying to sabotage the marriage? She filed for divorce only 72 days after their blowout $18 million wedding. The event reportedly provided a big payday for the Kardashians through product endorsements and a TV special.

“Kim got angry at her mom on the phone while they were in New York because of a photo shoot that she had to go to, that she didn’t want to do. Humphries was in the room, and told Kim to stop, and that she had diarrhoea of the mouth. Kim quickly turned her anger towards her husband and hung up on her mom, which happens all the time,” the source claims.
