In the past, Game Of Thrones has featured cameos from Sigur Rós (as wedding musicians) and Mastodon (as wildlings, of course), among others, and the latest musician to hit Westeros is Ed Sheeran. Entertainment Weekly reports that our reigning king of pop, apparently a favorite among Game Of Thrones cast members, will guest star on an episode of the show’s upcoming seventh season. Sheeran already has some experience with acting in medieval fantasy series, having played an “ambitious and deadly” knight on Kurt Sutter’s FX drama The Bastard Executioner. Also, he kind of looks like a hobbit, if that counts.
