Kim Kardashian is killing 'em with kindness.
In the April issue of ELLE UK, Friends With Kids star Jon Hamm, 41, complains: "Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated. Being a f-cking idiot is a valuable commodity in this culture because you're rewarded significantly."
The actor's comments didn't sit well with Kardashian, 31, who responded via Twitter Monday.
"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."
In his ELLE UK interview, Hamm also said the idea that reality stars can create successful businesses "doesn't make any sense" -- despite the fact that Kardashian and her family netted a collective $65 million in 2010.
