While Khloe Kardashian and Lamar Odom's marriage difficulties are playing out on the covers of every tabloid across the country, another marriage in the Kardashian-Jenner household is falling apart behind the scenes.

In Touch reveals that Kris and Bruce Jenner are ready to call it quits on their

22-year marriage, thanks to increasing tension between the laid-back athlete and his fame-hungry wife.

A friend tells the magazine that things have gotten so unpleasant between the two that they’ve already begun living separate lives.

They’ve had problems for a long time and have been separated for months,’ says the insider.

While Kris is trying to maintain the image of a unified front, it’s getting more difficult by the day, especially when she’s been in the habit of leaving her wedding ring at home.

“There were also promo photos for her talk show [Kris] that she wouldn’t approve because she realized she wasn’t wearing her ring in them,” says the source. “She made sure they never saw the light of day.”

Although the pair are still filming Keeping Up With the Kardashians together, that’s where their relationship ends.

"They don’t do anything together unless it’s filmed,” adds the friend. “They haven’t slept together in years and pretty much just have a business relationship at this point.”
