Maisie Williams a.k.a Arya Stark crashed into a fan's apartment to watch the worldwide premiere of the Game of Thrones season 6 on Sunday.

The 19-year-old gate crashed into a GOT 6 viewing party of some UCLA students and brought in snacks to dig in. She documented all the fun, and ultimate reactions of people on her Instagram.

The 12-part ' Surprise series', as we call it, started with a random tweet from William's official social media account where she urged fans to post pictures of their viewing parties.

"ANY @UCLA STUDENTS HAVING A VIEWING PARTY TONIGHT? TWEET A PICTURE OF YOUR PARTY USING #GAMEOFTHRONES FOR A SURPRISE," Williams wrote.

The actress then chose a lucky couple, who she named as Mark and Kate for the big surprise. William, as her Instagram says, went for a snacks shopping and amazed the couple and their friends with her appearance at their apartment an hour before the West Coast premiere.

"I found a couple, Mark and Kate, film students, who were throwing a party at their apartment, with a few friends. So at 8pm we left the hotel to go get snacks," Williams wrote in her second post.

And then it was some snacks shopping time...
