Kim Kardashian's best friend, reality star Jonathan Cheban was not impressed when actor Jon Hamm slated the star in a recent interview.

Us Weekly report Jonathan said: "I think Jon Hamm needs to just shut up and stop being such a mad man!"

Adding: "He needs to mind his own business, because Kim works hard. They do different things - it's a whole different world."

The ‘Mad Men’ star ranted to ELLE UK, "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."

But it looks like the Armenian beauty’s best friend Jonathan argued that Kim is more famous than him - and will be so for a long time.

He explained: "Put Jon Hamm in a mall, and more people will go up to the people working at the Burger King than they will to him.

“Bring Kim to a mall and there will be a riot. They're in two different businesses. Kim's pop culture and what people like."
