Ed Sheeran has made his highly-anticipated Game of Thrones debut!
And there's no mistaking it's him - it looks like he literally just stepped off stage, threw on a cloak and jumped on to set.
He appears in the show for a total of 40 seconds, and yes - he is singing (because he's Ed Sheeran).
Check out the scene below. It doesn't contain any major spoiler as far as we can tell - but a warning to those who want to avoid any GOT until they see the episode themselves!
