There is that feud going on between Jon and Kim Kardashian!

Jon called Kim a "f***ing idiot" and didn't apologize for it after she called his remarks "careless."

"It's good problems, it's a good kind of busy," Jon told Jimmy on Late Night.

Jimmy said, "You also had the Kardashian thing, that was not good problems."

"Well, that's not really a problem, is it?" Jon said replied with a smile.

"It depends on how you look at it, that's right," Jimmy agreed while laughing.
