Sophie Turner was recently invited to the Jimmy Kimmel show where she revealed the person behind that Starbucks cup blunder.
Turner told Kimmel on his night show that her husband, Joe Jonas video called her, and asked her the question every fan has had in their minds for so long now.
Kimmel played that video which made Turner and the rest of the audience laugh on the fact that her husband was being adorable by being her biggest fan.
Turner then told the fans once and for all who was responsible for the cup on the set which was unfortunately shot along with the scenes.
It was Emilia Clarke, who played the Mother of Dragons, Daenerys Targarian in the series who was alleged to be drinking from the cup and had later kept the cup in front of her, leading towards the blunder.
