There's no denying that Game of Thrones has grown to become a global phenomenon.

Millions of fans around the world know each character intimately. But you'll be surprised to know that the characters (or, at least their actors) exist outside of Westeros in the real world. That still doesn't stop it blowing people's minds when they see Tyrion Lannister doing his shopping or Gregor 'The Mountain' Clegane lovingly petting a tiny dog. Fans are still trying to get over the fact that Lord Varys actually has a full, thick head of hair in real life or that Septa Unella (the one who likes to shout 'shame') isn't a stony-faced nun but in fact a vivacious and beautiful woman away from the show. https://twitter.com/GameOfThrones/status/756640409711882240?ref_src=twsrc%5Etfw So just imagine what would happen if one of Game Of Thrones' most prominent characters went and got a new hair style. You know, someone like Sansa Stark who is instantly recognisable for her long, luxuriant ginger locks. People would go bananas. https://www.instagram.com/p/BDiixQtqosm/?taken-by=sophiet Well she did....and they did. Sophie Turner, who plays the oldest Stark daughter, and who we last saw helping Jon Snow liberate Winterfell and the North from the clutches of Ramsay Bolton, has gone blonde. We're not sure if she's trying to emulate a certain dragon-wielding Targaryen or if she wanted the latest Lannister look, but she looks very different to her character in the show now. https://www.instagram.com/p/BIdBCfihi3n/ She doesn't even give fans a reason why, simply commenting 'I did a thing' which got her 339,000 Instagram likes for the trouble. We don't know if it's Game Of Thrones related, whether she's taking the piss, or if she's got a new film role that requires her to be blonde. Fans were losing their shit over it though... https://twitter.com/DeniseAnnaa/status/759140917123112960 https://twitter.com/mtulls14/status/759113123668393985 https://twitter.com/PhlyinPhil12/status/759097314359201792 https://twitter.com/iamronelcollen/status/759689915948871680 https://twitter.com/amyhanks54/status/759413376732672000 https://twitter.com/SansaStarksMan/status/760109403148197888 https://twitter.com/scottsumrners/status/760006361908334592 https://twitter.com/Stingray_travel/status/759605880652460033
