Maisie Williams surprised several Los Angeles students by crashing their Game of Thrones viewing party.
The opening episode of the fantasy show's sixth season debuted in the U.S. on Sunday and as a result fans across the country had planned viewing parties to watch it with friends.
And Maisie, who plays Arya Stark in the series, decided to surprise one group of University of California students hosting a viewing bash by bringing them snacks in person.
She initially disguised her intentions in a post on Twitter, writing that a group of lucky partygoers she picked would only be receiving a Game of Thrones goody bag delivered to their door.
However the 19-year-old got in contact with a couple named Mark and Kate, film students at the university, and turned up outside their apartment with popcorn and crisps.
She revealed on Instagram how a shocked Mark greeted her, writing, "Firstly, I met Mark. The buzzer was broken so Mark came down to let us in. After exhaling a "HOLY S**T!", we hugged it out and he helped us inside."
Maisie and her host then hatched a plan to surprise his friends and girlfriend when she came up to his apartment by having Mark tell them they'd won the Game of Thrones prize while the actress hid.
"My favourite part is how excited they sound to win the swag, little did they know, I was just around the corner," she writes.
She then revealed herself to the shocked fans, tucking into Game of Thrones themed snacks her hosts had already made as well as her own nibbles.
After the viewing party, she signed off the succession of posts which documented her evening by writing, "I had the most amazing time, everyone was so welcoming and excited...Thanks to Mark, Kate and company for having us in your lovely flat. Enjoy the rest of Season 6."
