Game of Thrones fans are pointing out what appears to be a Starbucks Coffee cup next to Emilia Clarke's character Daenerys Targaryen in one scene from the latest episode of the biggest show on television.
In the show's fourth episode of its eighth and final season, the cup is spotted on a table behind actors Kit Harrington (Jon Snow) and Kristofer Hivju (Tormund Giantsbane) in a scene taking place in Winterfell.
Twitter was set ablaze with people criticizing the show for the major goof.
HBO has not yet commented on the blunder.
