Cara Delevingne slammed by Game of Thrones star

Richard Madden has branded Cara Delevingne "unprofessional" for her awkward interview on 'Good Day Sacramento'.

A conversation featuring the model-turned-actress giving short and blunt answers about her movie 'Paper Towns' on US television went viral in July and was dubbed one of the most cringeworthy chats ever, but 'Game of Thrones' actor Richard has criticised her behaviour insisting she should have been more polite to the interviewers as it's part of her job.

"It was unprofessional," said Madden. "It made her seem ungrateful. She showed her age. For 'Cinderella', I did six weeks of those interviews, where you get asked the same eight questions."

The 29-year-old went on to suggest she shouldn't have become an actress if she can't deal with the necessary publicity which comes with being in films.

"If you're not capable of doing that gracefully, then don't do it," he told Style magazine.

Cara, 23, hit out at critics following the interview by refusing to apologise and saying her sarcastic responses just showed she's "human".

She tweeted: "I am soooooo lucky and anyone who thinks I am unappreciative or ungrateful clearly doesn't know me.
