Jon Hamm has said his statement about celebrity stupidity was "nothing personal" against Kim Kardashian.

The Mad Men actor blasted the culture of celebrity in Hollywood which celebrated idiocy and name-checked Kim and Paris Hilton as he did so - causing Kim to retort he should not be so careless with his words - but he has now claimed he did not mean it as a direct attach on the 31 year-old.

"It's surprising to me that it has become remotely a story. I don't know Ms. Kardashian, I know her public persona. What I said was meant to be more on pervasiveness of something in our culture, not personal, but she took offense to it and that is her right."

After the outburst, Kim - who runs her own business in addition to modelling and appearing in various TV shows - claimed she had respect for the actor but told him he should think more about what he says.
