Don’t cross a Kardashian!

Kim Kardashian has used her Twitter account, harnessing the power of her 13.8 million followers, to slam Mad Men star Jon Hamm after he made disparaging comments about her and some of her fellow reality stars, Breaking Celebrity News is reporting.

In the April issue of ELLE UK, Hamm said: “Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated. Being a f***ing 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.”

Kim struck back on Monday, writing: “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.

“We’re all working hard and we all have to respect one another. Calling someone who runs their own businesses, is a part of a successful TV show, produces, writes, designs, and creates, ‘stupid,’ is in my opinion careless.”
