The pair could be on the verge of reaching one of the biggest divorce settlements in Hollywood history after it emerged they do not have a prenuptial agreement, RadarOnline.com has exclusively learned.
It means Bruce, 63, is legally entitled to a hefty part of the Kardashian brand's fortune made from their E! television show and entertainment empire.
“This is going to be a very bitter pill for Kris to swallow because when they divorce is finalized, she'll have to split half the family fortune with Bruce,” a source with knowledge of the situation revealed to Radar.
“Kris demanded that Kim and Khloe get prenups... but in a touch of irony, she didn't get one when she married Bruce.”
Among the assets to be divided up will be the couple's Calabasas, Calif., home -- said to be worth millions of dollars itself -- and a fleet of luxury cars.
But just like Kris, Bruce -- an Olympic Decathlon gold medal winner -- has built his own nest egg.
He was once reportedly worth a whopping $100 million that he'd amassed from endorsement deals such as Wheaties and his Bruce Jenner Aviation business, a corporate airplane sales company.
However, the extent of his fortune today and what's left is not publicly known.
"Bruce was the primary bread winner and he provided Kris with a luxurious lifestyle when they were first married," a source said.
"He had endorsement deals and was a very popular motivational speaker.
"But as the Kardashian brand and fortune grew, Bruce joked to Kris that she should have gotten a prenup so he couldn't take anything from her.
"Never in her wildest dreams would Kris have ever anticipated she could be losing the family fortune she worked so hard for. She won't give it up without a fight."
In 2012, Kris, 57, inked a whopper deal with E! for three more seasons of their hit TV show that was rumored to be worth more than $40 million — making it the most profitable deal in reality history.
“To say Kris is obsessed with money is an understatement," the insider added.
"She is obsessed with their family mansion and their luxury vehicles.
"Bruce likely won't fight Kris to keep the house. He'll probably ask that she just buy him out... which Kris won't want to do because it means spending her own money."
Said the source: "If they end up divorcing, one thing is certain -- Kris is not going to part with a penny more than she has to!"
