"I'm Ariel, minus the tail and the t**s," Williams captioned the shot, posted to her Instagram on Wednesday. "'A girl has no t**s,'" she added, referencing her Game of Thrones character Arya Stark's recent storyline.
Cheeky captions and all, Williams looks to be having a great time on her vacation. "Ah Italy, you are beautiful," the actress posted the same day, along with a snap of the country's blue skies and calm sea.
And the day before, it looks as if she was checking out the sights in Berlin, Germany.
Williams may be enjoying some much needed time off -- her character has been through quite a lot this season -- but there's still more Game of Thrones to be had -- or is there? The star recently opened up about how the show could be coming to an end.
"At the end of the read through of this season, I sat there thinking: 'God, they are setting up for the end,'" Williams told The Red Bulletin in March. "It's still no way predictable, but the feeling that this is slowly coming to an end is so so exciting, and terrifying at the same time. I can't wait to see it."
Despite the actress' comments, Thrones will be back for a seventh season -- and eighth, according to reports -- so Arya's storyline hasn't been wrapped up quite yet! We had some of our own ideas for Arya's future on the series (love interest, anyone?) -- see what Williams thinks of 'a girl' getting a little romance in the video below.
