9 Reasons Kris Jenner & Caitlyn Jenner's Fame War Is ON!

Uh oh! Looks like there is some serious drama going on between Kris Jenner and ex Caitlyn Jenner.  "Kris is not a fan of Caitlyn at all," a family inside reveals.  "She's extremely jealous of all the attention her ex is getting and can't stand hearing about it."

Kris feels threatened by Caitlyn's earning power.  The infamous momager has always taken a percentage of her family member's paychecks for herself.  Last fall, Caitlyn fired Kris as her manager, and now an insider says, "Kris is furious that someone else is reaping all the money from Caitlyn's success."

A source says that Kris "feels like she stood by Bruce for 25 years, and the least Caitlyn could do is keep her as her manager.  It's like the ultimate betrayal in her eyes." 

Kris is terrified that Caitlyn's new show could draw viewers away from her own programs--especially since daughters Kim Kardashian, Khloé Kardashian, Kourtney Kardashian, Kendall Jenner and Kylie Jenner have agreed to appear on it. "Kris sees this as a direct attack on her business, because it will essentially be Keeping Up With the Kardashians but without Kris," an insider explains.  

Ever since Caitlyn's big reveal on June 1, Kris has acted increasingly desparate for attention.  She has even taken to dressing like daughter Kim Kardashian, wearing outrageously revealing outfits.

Caitlyn's decision to exclude Kris from her future endeavors stems from a deep-seeded animosity toward her ex.  She made her feelings about Kris very clear in her Vanity Fair interview.  "A lot of times, she wasn't very nice.  People would see how I got mistreated," Caitlyn said.  She estimated that 20 percent [of my decision to divorce] was gender and 80 percent was the way I was treated."

Even if they pretend like their relationship is civil, friends say that Kris and Caitlyn have been secretly engaged in a dirty war, trying to one-up each other as much as possible. Caitlyn even hired some of Kris's employees! "All of the sudden, Kris' hair and makeup people were always busy when she needed them...Kris can't believe Caitlyn stole her glam squad!" says an insider.

Kris is planning to write a tell-all about her marriage to Bruce, a source says. "She's desperate to get revenge on Caitlyn. Kris told her: 'Lipstick won't make you happy.'"

Her inability to control the situation—from Caitlyn to her daughters to her own TV empire—is what has her most terrified. An insider spills, "Caitlyn has become America's sweetheart, and Kris is having trouble winning anyone—even her closest friends and family—over to her side. This could be the end of her reign!"
