Cara Delevingne says Nat Wolff makes her job ''so easy''.

The 22-year-old actress has praised her 'Paper Towns' co-star and John Green, the author of the novel on which the film is based, for their continued support.

Captioning a photo of the three of them at a press conference, she wrote: ''You make my 'job' so easy @natandalex @johngreenwritesbooks. (sic)''

Nat shared a similar sentiment, writing: ''Another 2 people I could travel the world with in one week and not get tired are the wonderful and talented @Caradelevingne & @jakeschreier. (sic)''

Meanwhile, Cara previously admitted she was ''terrified'' to leave modelling for the film industry.

She said: ''The thrill of acting is making a character real. Modelling is the opposite of real. It's being fake in front of the camera.

''I'm not sure I understand what fashion is anymore. I admit I was terrified to leave. I mean, the bubble gives you a kind of dysfunctional family. When you're in it, you get it. And the second you're out of it, you're like, 'What the hell just happened?'''

Cara - who has starred in high-profile campaigns for luxury fashion brands including Burberry and Chanel - previously admitted fashion left her feeling ''empty''.
