'Mad Men' Star Jon Hamm -- Kim Kardashian and Paris Hilton Are 'F**king Idiots'

Don Draper isn't one to mince words, so it's only fitting that "Mad Men" star Jon Hamm DESTROYED Kim Kardashian and Paris Hilton in a recent interview ... calling them stupid and "f**king idiots."

Hamm appears in next month's issue of ELLE UK, where he said, "Whether it's Kim Kardashian or Paris Hilton or whoever, stupidity is certainly celebrated. Being a f**king idiot is a valuable commodity in this culture because you're rewarded significantly."

Clearly Hamm was not in his right mind when he gave the interview ... because he also said he doesn't "even consider myself handsome."
