Not only are they both global superstars with bajillions of streams combined, Ed Sheeran and Elton John are also firm friends, and now, they've put their heads and their talents together and released a Christmas single!
Speaking to Dermot and Dave back in October, Ed revealed that he and Elton 'speak every day' and that they were working on the single.
And now, we finally get to hear it!
'Merry Christmas' is out now and it's all for a good cause! All proceeds will be donated equally between the Ed Sheeran Suffolk Music Foundation and the Elton John Aids Foundation.
