Speaking about the memorable moment in a video posted to Game of Thrones' Twitter account, she spilled: ”I was quite young and I had such a big imagination.

She continued: "I remember it being really late and being tired but also being like… having a good time.
“I was flicking pigeon pie at Sophie [Turner]. That was my first day on set."
The star divulged: “They were saying: ‘Can you just like try and get it like right on her cheek?
