Kim Kardashian is a mad woman after learning that Jon Hamm -- aka Don Draper on Mad Men -- insulted her and fellow celebutante Paris Hilton.

In an interview with Elle EK, the Friends with Kids star slammed reality stars and the culture of talentless celebrities.

Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated, Hamm told Elle UK. Being a f--king idiot is a valuable commodity in this culture because you're rewarded significantly. Incuriousness has become cool... It's celebrated. It doesn't make sense to me.

On Monday afternoon, Kardashian responded to his comments via Twitter.

I just heard about the comment Jon Hamm made about me in an interview. I respect Jon and I am a firm believer that everyone is entitled to their own opinion and that not everyone takes the same path in life, she wrote in a massage linked to her Twitter feed. We're all working hard and we all have to respect one another. Calling someone who runs their own business, is a part of a successful TV show, produces, writes, designs, and creates, 'stupid,' is in my opinion careless.

Hamm, who is set to return to the small screen with the season five Mad Men premiere later this month, was singing a different tune last week when talking about his longtime partner Jennifer Westfeldt's hard work on Friends With Kids, the actress/writer's directorial debut.

People are going to be naturally predisposed to dislike sisters who are doing it for themselves. And it's crazy, and it's not just men; it's very often other women, Hamm told the New York Times. There seems to be this expectation of: 'Hold on, lady. You just stay in your place. Don't try to reach for too much.

Hamm also addressed his and Westfeldt's marital status in the Elle UK interview.

The flip answer is, if it ain't broke don't fix it, Hamm said. The better version of that is, that any relationship is a day-in-day-out process.

Having a piece of paper serves to remind you of your commitment, he continued, but we do a pretty good job of reminding each other.
