"They asked her very politely not to drag their name into conversation, but she couldn’t seem to stop herself and it’s really put their noses out of joint," a source told the publication.
"Cait’s lack of a filter has always been an issue, but using them for publicity and popularity is a step too far," the source added.
As we know, Caitlyn was in fact under strict orders not to say a word about the family and has now been slapped with a multi-million dollar lawsuit for violating her gag order.
During her time in the jungle, Caitlyn spilled about the famous family, even revealing how much money Kylie Jenner spends monthly on her security alone, which is a huge breach of the young billionaire's privacy.
"I bet you Kylie will spend anywhere between [$300,000] and $400,000 a month. A ton of money," Caitlyn told jungle-mate Cliff Parisi.
She even said that she thinks it is "sad" that they have to rely 24/7 on security.
"They’re used to it. They’ve been doing it forever. They like the security guys there," she shared.
The contract was drawn up by Kris Jenner and Keeping Up With the Kardashians co-creator Ryan Seacrest.
"This contract was handed to all participants in the show and means that Caitlyn could be in hot water," a source told Daily Star Sunday.
'The contracts that she signed were designed to keep inner secrets about the family a secret and protect the show," the report continued. "Technically this could pose legal dramas for Caitlyn," Talking about the family, connected to the show, is a grey area."
It wasn't just Kylie that Caitlyn blabbed about either. She also dragged Khloe Kardashian's name through the mud.
She admitted that Khloe was the hardest family member to open up to during her transition in 2014 because she was "pi**ed off about something" and that she "didn't know what her issues are".
"I went through every kid and Khloe for some reason was pi**ed off about something through this whole process, it’s been five or six years and I’ve really haven’t talked to her since," Caitlyn told fellow jungle-mate Roman Kemp.
"We were really close, I raised her since she was five years old, I really don’t know what her issues are."
