Guess Jonathan Cheban isn't a Don Draper fan.
The reality star and Kim Kardashian's best friend went off on Jon Hamm — who famously criticized Kardashian, 31, in a recent interview — during a chat with Us Weekly on Tuesday night.
"I think Jon Hamm needs to just shut up and stop being such a mad man!" the Spin Crowd star sniped at Ocean Drive magazine's bash for cover star Nicole Richie at Vesper in Miami Beach, Florida. "He needs to mind his own business, because Kim works hard. They do different things –it's a whole different world."
Acclaimed Mad Men actor Hamm, 41, 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." The Golden Globe winning hunk later said the comments weren't "personal" — but they were, he insisted, "accurate."
But Kardashian's bestie Cheban argued that she is more famous than Hamm — and will be so for a long time.
"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," he told Us. "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."
Cheban's not sure about Hamm's staying power. "It's a lot of work, and she's here to stay. Let's see where he is after Mad Men."
Mad Men's fifth season premieres this Sunday on AMC.
