This article will not contain any spoilers for upcoming episodes of Game of Thrones, although the video content has spoilers for what has happened so far.
Many of Emilia's fans flocked to her page to comment.
Turner went onto explain that everybody on the crew has the same cups. "Emilia Clarke. She's the culprit".
The actress not only defended herself, but rather blamed co-star Emilia Clarke for the slip while appearing on "The Late Show with Jimmy Fallon" on Friday night, May 10.
Sophie Turner, 23, wants fans to know that Cup-gate on Game of Thrones - aka when a Starbucks cup appeared in the show that takes place thousands of years ago - was not her fault, despite what husband Joe Jonas, 29, wants some to believe!
Fallon then pulled out a photo showing Turner holding the same cup while posing with Bella Ramsey, who plays Lyanna Mormont on the show.
HBO has since digitally removed the cup from versions of the episode on the HBO Go app.
"TBH we're surprised she didn't order a Dragon Drink", the company said on Twitter, referring to its summer menu addition of a bright pink fruit and coconut milk beverage that contains the tropical dragon fruit, also known as pitaya.
"Nowadays you can't believe what you see because people can put things into a photo that really doesn't exist, but I guess maybe it was there, I'm not sure", she said. She added, "And also, we all have the same cups for all of our water and tea and everything". Momoa had dropped by the set to visit his old coworkers, and Clarke must have forgotten about her cup.
Emilia's snap comes after she revealed she's still "determined to lead a normal life" despite shooting to fame on one of the biggest TV shows.
Let's hope no more rogue cups of tea are left in Winterfell in the last two episodes.
