The mafia's code of silence is nothing compared to the Kardashians'! RadarOnline.com has learned that new mom Kim Kardashian is lashing out at her BFF Jonathan Cheban and threatening to ban him from Keeping Up With the Kardashians if he talks about her on a new show.
"Kim is furious with Jonathan because he's going to be on Celebrity Big Brother in the UK and she's afraid he's going to spill all her secrets," a source told Radar.
"She gave him an ultimatum, telling him that she didn't want him to do the show and if he did, she would stop talking to him."
The source explained that Kardashian, 35, warned Cheban, 41, not to gossip about her.

And it wasn't a one-time meltdown.
"Kim is growing increasingly protective of her personal life and she is worried that all Jonathan is going to do is talk about her while he's filming," the insider explained. "She told him he had better not spend the whole time talking about her."
