Cara Delevingne was told to ''take a little nap'' and ''get a Red Bull'' during an interview about 'Paper Towns'.

The model-turned-actress was on American breakfast show 'Good Day Sacramento' to promote her new flick and after the interview became awkward, the TV anchors made little digs at the star.

Towards the end of their talk, was when it became most heated.

When the show's anchors asked if Cara was annoyed, she said: ''No, I think it's just you.''

To which they responded: ''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?''

The interview got off to a bad start as they introduced her as ''Carla''.

The show's host persisted and asked if she found it hard focusing on several projects at one time.

She responded: ''No. I don't know where that comes from.''

The 22-year-old beauty then gave several sarcastic responses, including about her 'Paper Town's character, Margo.

Asked if she can relate to her, Cara joked: ''No, I actually hate her.''

Variety reported that the hosts apparently continued to make digs about Cara off the camera.

An anchor said: ''You make $5 million for six weeks of work, you can pretend to talk to 'Good Day Sacramento' with some 'oomph'!''
