Maisie Williams and Sophie Turner met when they were only 12 and 13 years old, respectively, but it didn't take long before they realised they were soulmates. In fact, it was during their first Game of Thrones screen test when "there was undeniable chemistry," and they knew they had to star in the show together. Ahead of the highly anticipated final season of GoT, the onscreen sisters and real-life besties sat down with Rolling Stone to discuss the "firsts" in their relationship – the first time they met, the first time they went to the United States together, the first time they were proud of each other, and so many other incredible experiences.
The two have very different personalities on the show, but in real life, they couldn't be more obsessed with each other, and we can't get enough of "Mophie" ourselves. Maisie and Sophie gush over each other and talk about their "best friend day ever," which included two-for-one cocktails, shopping for matching sunglasses and backpacks, a Red Hot Chili Peppers concert, and of course, ended with getting matching tattoos. Watch the video above, but be prepared to smile for 12 minutes straight.
