Bruce Jenner is allegedly preparing to file to divorce from Kris Kardsashian.
The 63-year-old Olympic gold medallist is said to have consulted a lawyer after 21 years of marriage, because he is fed up with Kardashian, 55, who manages her entire family's careers, flirting with younger men and her increasingly large ego.
"Bruce feels that Kris treats him like a doormat and he's had enough," a source told the National Enquirer.
"She constantly belittles his appearance and complains to mutual friends that he's a boring old fart. Then she has the gall to flaunt her relationships with younger guys in his face!"
Jener shares two biological children with Kris - daughters Kendall, 17, and Kylie, 15 - but they both have four other children each from previous relationships, including her world famous daughters Kim, 32, Kourtney, 33, and 28-year-old Khloe Kardashian.
"He hates it when cronies at the Country Club jokingly call him Bruce Kardashian. Kris is continually perceived as the moneymaker and the one who wears the pants in the family, and he's sick and tired of the humiliation."
Jenner has reportedly already met with a lawyer to discuss a legal separation, which would involve dividing up the couple's estimated US$155 million (NZ$190.8 million) fortune.
"One of Bruce's pals, who's a sports entertainment lawyer, has helped Bruce value the assets of the Kardashian-Jenner empire if he moves forward with a split," said an insider.
"He's also talked to a divorce attorney buddy about potential custody arrangements for his two girls with Kris."
