Kim Kardashian recently warned her friends who threaten to spill too many of her secrets to the public.

Word is Kanye West's 35-year-old wife and "Keeping Up With the Kardashians" reality star lashed out at best friend Jonathan Cheban over her growing suspicions he might spend too much time talking about her and spilling her secrets when he appears on a new "Celebrity Big Brother" show.

"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," a source told Radar Online. "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 he does she might not let him do 'KUWTK' anymore."

Kardashian's meltdown doesn't appear to be a one-time thing. Reports are she is growing more and more protective of her entire lifestyle.

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

Kardashian's privacy concerns may only grow over time, given she and West just this month gave birth to their second child. Saint West was born several weeks earlier than expected, and word is Kardashian is already in the midst of planning a family trip to Israel to have him baptized.

"She wants to take Saint to Jerusalem to get baptized like they did with North," a source said, adding that West and daughter North West will also be part of the traveling party.

Saint West is expected to be feted at the Armenian St. James Cathedral in Jerusalem's Old City, the same place where the ceremony for North West was held in April 2015.
