This is what goes on in the 'Game of Thrones' cast's secret WhatsApp group

Have you ever wondered what it would be like to be on Game of Thrones? Assuming you weren't one of the unfortunate cannon fodder who get slaughtered by a dragon or murdered in cold blood because Joffrey was vengeful, vindictive or... because he was bored.

It would be amazing to be a fly on the wall as Cersei planned her next devious plot, or as Tyrion and Daenarys talked strategy, or as the family drama between the Starks reached fever pitch. But as we all know, that's impossible; Westeros is a made-up place, and the closest you'll ever get is watching the show, or maybe by checking out some of the behind-the-scenes footage.

But for me, that's not quite enough.

Game of Thrones, of course, takes its final bow later on this year, and life won't be the same without this HBO fantasy epic, but did you know there's a completely new view on how the show operates that happens once the cameras turn off?

Yes, Thrones fans - you can get your fix in a decidedly new way by checking out what Maisie Williams (aka Arya Stark) had to say about a Game of Thrones WhatsApp group. It's like the WhatsApp group you have at work, except one of your colleagues is in the latest X-Men film.

This came via a revelation at the Glamour Beauty Festival in London last week, but what exactly do the cast of Game of Thrones talk about? Is it spoilers? It's not spoilers: as Williams revealed, they just like to post funny pictures of one another.

“We have a Game of Thrones WhatsApp and people just post really funny pictures of one another from various seasons," she explained, talking in detail about how the cast feel like "one big family". "I think there was a rule that these do not go on Instagram… but I’m definitely going to put them on Instagram," Williams cheekily revealed.

As we all know, Maisie Williams has a really close relationship with Sophie Turner, who plays Williams' on-screen sister, Sansa Stark. But what you might not know is that apart from Turner, 21-year-old Williams has a really special bond with Lena Headey, who plays the villainous Cersei Lannister on the show.

"I've been close with her for a long time. When I first met her she didn’t have any kids and I was 12-years-old and now she’s a mother of two," revealed Williams.

"We’ve been with each other for these crazy times in our lives. Knowing someone for a decade is huge and she’s always treated me like a grown up. She always respected me on a real level and for that I’m so grateful."

Williams also revealed she's talked to Joe Jonas, Sophie Turner's fiancé, about the ending of Game of Thrones, but you'd have to get her "very drunk" in order for her to let a spoiler slip. I guess we're going to have to wait until April to find out what happens on the final season of Game of Thrones.
