The British beauty sat for an interview for Good Day Sacramento via video link from New York, where the usually-energetic star appeared to answer questions about her new movie Paper Towns in a tired and sarcastic manner.

The interview started with a female reporter accidentally introducing Delevingne as 'Carla', and when asked if she had read the Paper Towns novel, Delevingne replied, "No, I never read the book, or the script actually. I kind of winged it... no, of course, I love the book."

A male co-presenter later took Delevingne to task over her apparent attitude, saying, "I saw you in London a couple of weeks ago on TV and (you) seemed a lot more excited about it (Paper Towns movie) than you do right now. Are you just exhausted?"

Taken aback, the model replied, "Oh... no, I mean, I'm still very excited. The premiere was last night... But I'm not any less excited than I was a couple of weeks ago. Maybe I had a bit more energy. It's the morning; don't be mean."

The chat was cut short after the female anchor added, "You seem a bit irritated, perhaps it's just us", to which the Brit fired back, "Yeah, I think it's just you."

Video footage of the interview has since gone viral, but Delevingne is adamant a cultural divide is to blame for the tense exchange.

Taking to on Wednesday (29Jul15), she writes, "Some people just don't understand sarcasm or the British sense of humour".
