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)"
Wolff 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, Delevingne 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?'"
Delevingne - who has starred in high-profile campaigns for luxury fashion brands including Burberry and Chanel - previously admitted fashion left her feeling "empty".
