Kim Kardashian to Jonathan Cheban: Keep Your Mouth Shut, Or Else!

Well, this is a pickle.

Jonathan Cheban and Kim Kardashian: MailOnline's Yacht Party

What happens when the person who made you famous starts giving you ultimatums that could affect your career?

Dunno, but publicist Jonathan Cheban is in the middle of finding that out. Kim's confidant and sometimes Keeping Up With The Kardashians star has risen to fame as her "best friend."

Cheban has been there for the big moments; he helped transport Kardashian's first engagement ring (from Kris Humphries) from the east coast to Los Angeles, and even helped her steal Kourtney's breast milk to treat her psoriasis on Kourtney & Kim Take Miami.

(Yes, we had that fact at our disposal. It's a gift.)

Now, that friendship is being tested, however, as it's revealed that Cheban has signed on for the upcoming season of Celebrity Big Brother in the UK (past contestants include Jenna Jameson, Farrah Abraham, Perez Hilton, Heidi Montag and Spencer Pratt).

Kim is furious with Jonathan because he’s going to be on Celebrity Big Brother in the UK," a source told Radar Online.  

"She’s afraid he’s going to spill all her secrets."

Cheban has been accused by Kourtney and others in the past of feeding stories to the tabloids, which played out on an episode of Kourtney & Khloe Take The Hamptons.

"She [Kim] 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. 

"Kim thinks that fame has gone to Jonathan’s head. She told him that she doesn’t want him to do the show and if she does she might not let him do KUWTK anymore."

As her own family grows, Kim has become a little more protective of her personal life.

The fact that Jonathan could potentially thrust that part of her into the spotlight has Kim worried.

“She told him he had better not spend the whole time talking about her," the source added.
