Kris and Bruce Jenner prefer to live apart.

The couple - who have been married for 22 years and have children Kylie, 15, and Kendall, 17, together - bought a second home in California, where Bruce likes to spend much of his time.

Kris' daughter Khloe Kardashian told 'The Tonight Show' host Jay Leno: ''Well, they're not having problems but they still like to live apart, which is definitely different.

''In my house, there is a man room for my husband Lamar [Odom]. A room, not a different house. I think they took my idea and ran with it and they got another house. Bruce stays there sometimes.

''It's in the same state, a different city. I'm not for that, but you know, to each their own. I don't compare relationships. I just think a little too much time apart maybe isn't the best thing.''

While Khloe doesn't approve of their unusual living arrangement, she says Kris and Bruce are happy with their arrangement.

She added: ''They're like, 'Don't judge us. We've been married [22] years'. I'm like, 'I know people that have been married longer that still live together.' ''
