But, during a recent interview with Jimmy Fallon, Soph revealed that she thought it was actually Emilia Clarke who brought the cup onto the set.
“Let’s clear this up. That's in a different scene,” she said about the photo. “Also, we all have the same cups for all of our water and tea and everything, so…I mean look who it's placed in front of: Emilia Clarke. She's the culprit.”
While Emilia has yet to respond to Sophie’s cheeky admission, she did post a pic to Instagram where she is also holding a similar cup!
“Did I just stumble upon the truth here?! The cup bearer does not drinketh the Starbucks tea...” she wrote.
While we’ll never know who is responsible, we have found this whole situation pretty hilarious.
