Cara Delevingne has revealed the 'Suicide Squad' cast have their own message thread.

The 23-year-old model-and-actress plays Enchantress in the anti-hero DC Comics movie and says she and her co-stars, which include Will Smith (Deadshot), Margot Robbie (Harley Quinn), Joel Kinnaman (Rick Flag) and Jai Courtney (Captain Boomerang), have become so close that they chat on their phones all the time.

During an appearance on 'Jimmy Kimmel Live!', Cara said: ''We have a text thread called 'Suicide Squad For Life' and we talk, basically every day.''

When asked if Will Smith was on this text thread by host Jimmy Kimmel, she replied: ''Yes, yes he is ... he makes time for the squad life, you know that's what happens.''

'Suicide Squad' - directed by David Ayer and is produced by Zack Snyder - focuses on a mercenary team of super villains who are assembled by the US government to carry out military missions.

The movie is part of Warner Bros' DC Extended Universe and will feature an appearance from Ben Affleck as Batman and Jared Leto as The Joker.

It will hit cinemas on August 5.
