Maisie Williams of the hit HBO series “Game of Thrones,” pops out with her newest hilarious prank. She played the trick on some of her most loyal supporters during a recent trip to a comic and collectibles store in Santa Monica.

The 19-year-old actress, who plays Arya Stark in the fantasy show, mystified her fans when she pretended to be a shop assistant called Loraine at the hobby shop.

Proving that the “cyberbully” cutie doesn’t take herself too seriously, Williams joked: “Wait, you think I’m this?” pointing towards a toy model of her character Arya.

“This is a little boy. This looks nothing like me.”

While most customers swore up and down that they identified her from “Game of Thrones” Season 6, some left with a suspicious state of mind after the English teenager refused to drop the prank, reports Mirror.

“I was thinking I recognize you,” Williams said in joking tone. “Where do I know you from?”

“I’m really sorry, I get this all the time,” she added, insisting they call her Loraine.

Her mission in collaboration with her forthcoming Nylon magazine cover shoot was to give away some free stuff from the show to unsuspicious fans; however, the prank quickly turned hilarious after the Bristol-born actor asked her customers to act out scenes from the series.

At last, when some customers were adamant that they recognized her from “Game of Thrones,” Williams offered free goodies in exchange for acting out scenes from the show.

Williams captioned one of her most recent Twitter posts as “THIS WAS MAD FUN” that expresses her fun-filled experience with her fans.

This is one more time the adorable starlet proved that not only she can entice her fans onscreen, but also on her downtime.
