Kim Kardashian was highly offended by the negative comments Jon Hamm had to say about her not too long ago.  In April's issue of Elle Magazine, Hamm called Kim K and Paris Hilton "F*cking idiots that people turn into a valuable commodity."  

Hamm later addressed his comments on the Today show, stating:

"I don't think my comments were careless. I think they were accurate."

Well, Kim K and Jon Hamm were on the set of 30 Rock together doing a live show, and the two ended up burying the minor feud between them.  Kim allegedly told one of her friends that she and Hamm "laughed it off" and that Jon was "very respectful" when they spoke.
