The 'Rather Be' hitmakers - who took home two gongs from The 60th Anniversary Ivor Novello Awards in London last night (21.05.15) - have revealed they've been busy in the studio working on new music with the 34-year-old star.
Jack Patterson said: ''We've been working with Alicia Keys, which has been pretty amazing.''
The 28-year-old star - who, together with Grace Chatto, Luke Patterson and Neil Amin-Smith makes up the group - confessed he was unable to control his nerves upon meeting the 'Empire State of Mind' singer.
He said: ''It was intense. I've grown up listening to her music and I was shaking quite a bit. It was difficult to get going.''
The 'Real Love' hitmakers - who also recently recorded with Marina & the Diamonds - were presented with the award for Most Performed Work as well as the Best Contemporary Song accolade for 'Rather Be', which was written by Jack and songwriter James 'Jimmy Napes' Napier.
The quartet fought off stiff competition from Sam Smith's 'Stay With Me' and George Ezra's 'Budapest' in the most performed work category.
