"Kim would never admit that she's jealous of Kendall. She's well aware of Kendall's escalating fame and Kim's always backhandedly telling Kendall, and all her family, that she's the reason they're rich and famous," a source told HollywoodLife.com

In the preview for the 10^th season of their hit reality show, Keeping Up With The Kardashians, Kim yells at sister Kourtney Kardashian and tells her that she bought her a career. In one conversation, Kim said, "I'm not buying her shoes, I bought her a f**ing career."

"Kendall will bring up things that she's doing, working on or projects that she's been offered and Kim will play nice and be happy for her, but will immediately find a way to make the conversation about her. She'll say things like, 'Oh, that's nice Kendall. I remember when I did that,' or 'I remember when I was first offered...' She's always downplaying Kendall's success when she should be encouraging her more and jumping for joy," a source revealed.

"If Kim had it her way, her entire family would bow down to her every morning. She wants every one of them to know that if it weren't for her, none of them would be where they are today," the source adds.

It must be hard for Kendall to share her successes when sister Kim is always there to downplay the conversation and make it about her.
