Kim Kardashian appeared with her sister Kourtney on The Late Show with David Letterman this week, where she was grilled by the late night host about when she was going to "wrap things up" with her still-husband Kris Humphries.

Kim admitted that she's trying, "it's a process," and that she just wants to move on.  She also explains that Kris is suing her for an anulment, claiming that she only married him for publicity. Kim says she would love to give her husband an annulment, but then that means she would have to admit to the fraud. 

Kourtney came to her sister's aid and said "I think if she was going to do it for publicity, she'd pick someone that people knew."

Ouch. Kourtney & Kim: 1, Kris Humphries: 0.
