She might be one of the most successful models in the world, but even Cara Delevingne gets moody sometimes.

During an appearance on US morning show Good Day Sacramento, the 22-year-old appeared disinterested and irritable, prompting the hosts to tell her to “take a little nap”.

In a segment promoting her film Paper Towns, one anchor introduced the model as “Carla” and the interview went dramatically downhill from that point, with Delevingne shooting sarcastic responses back to every question.

Asked if she found it easier to focus when busy, Delevingne responded: “No. I don’t know where that comes from.”

When one anchor pointed out she had seemed more enthusiastic about the film at a prior press event, Delevingne became visibly agitated.

“I saw you in London talking a couple of weeks ago on TV and you seemed a lot more excited talking about it than you are now, are you just exhausted?” the host asked.

“It’s the morning, don’t be mean,” the actress retorted adding, “I think it’s just you”.

“We’ll let you go then, how ’bout that?” one anchor said. “Why don’t you go take a little nap, maybe get a Red Bull?”

Once Delevingne was safely off air, the trio of hosts vented their frustrations, with one declaring she was “in a mood”.

“You make $5 million for six weeks of work, you can pretend to talk to ‘Good Day Sacramento’ with some ‘oomph’!” another added.
