Game of Thrones owes part of its success to the terrific performances of its younger actors, but one of those "children" has an upcoming spread in Vogue in which she looks all grown up. Who is it? The gorgeous Sophie Turner, of course!

Sophie, who plays Sansa Stark on the hit HBO fantasy, will be appearing in the upcoming December issue of Vogue in a glamorous shoot by photographer Patrick Demarchelier, and publicist Alexa Pearson tweeted this tease of the shoot.

Sophie, who will turn 18 in February, has grown up before our eyes over the past three years as the eldest Stark daughter on Game of Thrones, and she’s never looked more like a lady than in this gorgeous promo photo from the spread.

Even though Sophie is technically almost an adult now, that definitely doesn’t make her character Sansa’s marriage to the much older Tyrion Lannister (Peter Dinklage) last season any less creepy! And we don't even want to get into Littlefinger's all too disturbing interest in her...

Are you surprised by how grown up Sophie looks? Let us know in the comments below!
