It's finally here - the long-awaited first single from Adele's new album '25'.

Moody piano ballad 'Hello' was announced yesterday and is available to buy and stream from today.

The accompanying video was directed by Xavier Dolan and was shot in mid-October in Montreal. "It was a privilege to direct the music video for Adele's beautiful, heartbreaking song,” he said. “When I first heard it, all the images were already running by so clearly in my head - and her trust and generosity allowed me to create freely."
