Game of Thrones star crashes viewing party

Game of Thrones actress Maisie Williams has crashed a viewing party for the debut episode of the hit show's sixth season.

Williams, who plays the morally ambiguous Arya Stark, used her Twitter account to issue the call for a party to crash.

"Any @UCLA students having a viewing party tonight? Tweet a picture of your party using #GameofThrones for a surprise," the actress wrote.

After selecting a party to attend, Williams headed off to stock-up on snacks and documented the journey on her Instagram.

True to her word, the actress arrived at the party and watched the highly-anticipated episode with the college kids.

But not before those gathered lost their minds when Williams walked through the door and made good on her offer.

A video posted to Instagram shows the students grappling with joy and utter disbelief as Arya Stark herself walks into the living room.
