Jonathan Cheban, one of the men who run a New York City public relations firm, slammed actor Jon Hamm for trash-talking celebrity socialite Kim Kardashian.

It all started when Hamm bashed Kardashian in an interview with Elle UK, saying: “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.” After coming under fire, award-winning actor later stated that his comments weren’t “personal” – but he insisted they were, “accurate.”

Celebrity publicist Jonathan Cheban, who also happens to be a friend of Kim Kardashian, was clearly not amused with such remarks from Jon Hamm.

“I think Jon Hamm needs to just shut up and stop being such a mad man!” Cheban said at an Ocean Drive party Tuesday night. “He needs to mind his own business, because Kim works hard. They do different things – it’s a whole different world.”

The celeb publicist Jonathan Cheban also added that Kim Kardashian is more famous than Jon Hamm and will be relevant for longer than the Emmy winner.

“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,” Jonathan Cheban said.

“It’s a lot of work, and she’s here to stay. Let’s see where he is after Mad Men.”
