Game of Thrones fans know that the show can be a real heartbreaker. With its constant death, rape, and general misery, watching it every week can sometimes feel daunting (but oh dear God, we can't for the season seven premiere [1] on Sunday!). Thankfully, the cast and their happy and silly personal lives [2] give us the strength we need to keep going. In addition to the stars hanging out in real life [3], the character of Gregor "The Mountain" Clegane also makes us smile in ways we never thought he would. When he's not (probably) standing guard next to Cersei [4] on the show, he's hanging out with his adorable little dog, a Pomeranian named Ástríkur, in real life. Icelandic actor Hafpór Júlíus "Thor" Björnsson, who plays the massive killer, frequently takes to Instagram to share photos with his best pal, and they are too adorable for words. Do yourself a huge favor and keep scrolling to see the sweetest pair in the Seven Kingdoms!
