Jon Hamm has lashed out at Kim Kardashian again.

The hunky 'Mad Men' actor - who recently called the reality TV star a ''f***ing idiot'' - says he doesn't want to be known simply as a sex symbol because then he ''might as well be a Kardashian and have a sex tape'', a reference to Kim's leaked erotic video with former boyfriend Ray J.

Jon told Time Out London: ''The sexy thing is so ephemeral and meaningless other than in the world of selling magazines. Who cares, when it's reduced to just that? You might as well be a Kardashian and have a sex tape.

''It's not for me to define. It's exclusively in the purview of others and I can't remotely be a part of it. I guess it's better than the alternative. I mean, what's the opposite of a sex symbol? A person who makes children cry when they see their picture?''

Jon and Kim have been involved in a war of words ever since he blasted the 'Keeping Up With The Kardashians' star for being famous for being stupid.

Jon said: ''Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated. Being a f***ing idiot is a valuable commodity in this culture because you're rewarded significantly.''

Kim then fired back on twitter, saying: ''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.''

Jon later reiterated his comments, saying: ''I don't think they were careless. I think they were accurate.

''It's a part of our culture that I certainly don't identify with, and I don't really understand the appeal of it other than in a sort of car crash sensibility. And it's not something that I partake in or enjoy, but it is what is and here we are.

''There are a lot of channels on the dials and those channels need to be filled up with things... It's different strokes for different folks.''
