Ryan Gosling's musical credentials have already been checked in recent times thanks to his role in 'La La Land', but the actor has gone one step further by duetting with an actual musician.

Lykke Li has kept quite a low profile over the last few years, releasing her last album 'I Never Learn' in 2014 - but now the Swedish star is exploring her options with a role in Terrence Malick's new music-themed film 'Song to Song'. It's her second acting role, following her casting in Swedish crime film 'Tommy' in 2014.

Malick's film also features cameos from the likes of John Lydon, Red Hot Chili Peppers, The Black Keys and Iggy Pop alongside actors Michael Fassbender and Rooney Mara - but it's Gosling's duet with Lykke Li that's generated the headlines since it premiered at SXSW the other day.
