The theme song of Daniel Craig's upcoming James Bond film, No Time To Die, written and performed by the pop sensation Billie Eilish, is out.

The 18-year-old singer, who has co-written the song with her brother Finneas O'Connell, is the youngest artiste in history to record the theme track for the long-running spy franchise.

Produced by Eilish, Finneas and Stephen Lipson, the Bond theme song has orchestral arrangements by Hans Zimmer and Matt Dunkley and guitar from Johnny Marr.

In a statement, Eilish said, "It feels crazy to be a part of this in every way. To be able to score the theme song to a film that is part of such a legendary series is a huge honour. James Bond is the coolest film franchise ever to exist. I'm still in shock."

With her track, Eilish follows in the footsteps of British singers Adele and Sam Smith, who won an Oscar each for their songs in Skyfall (2012) and Spectre (2015), respectively.

The singer, who recently won five Grammy awards, will be performing the song for the first time at the Brit Awards in London on February 18.

The Cary Fukunaga-directed film also features Ralph Fiennes as M, Naomie Harris as Moneypenny, Ben Whishaw as Q, Rory Kinnear as Bill Tanner, Jeffrey Wright as Felix Leiter, Lea Seydoux as Madeleine Swann, and Christoph Waltz as Ernst Stavro Blofeld.

New cast members are Rami Malek, Ana de Armas, and Lashana Lynch.

No Time to Die will be released worldwide in April.
