He might be the size of a house and most famous for crushing a man's head in through the eyes with his bare hands (although that wasn't real) but it turns out that The Mountain must have a softer side to him.
Hafþór Júlíus Björnsson has now married his long-term girlfriend, Kelsey Morgan Henson, proving that size isn't everything. She's only 5"2, compared to her new husband's 6"9.
The actor, who has starred in HBO's Game of Thrones as Gregor Clegane since Season 4 announced the marriage on Instagram, saying: "It is with great pleasure that I now get to call Kelsey Morgan Henson my wife!"
That's about all we know, except for the fact that it looks as if the wedding took place in Thor's native Iceland. That's only because the few photos that there are look like the landscape of the Scandinavian country, and there was an Icelandic wedding photographer tagged in the post.
It's not for certain, but it's a pretty good bet that's where they were.
Björnsson's new wife - who is a 28-year-old Canadian - also shared the happy news on her Instagram, posting: "Looking forward to pulling this big guy around for the rest of my life.
"@thorbjornsson I love you now and forever and promise to stand by your side through all that life throws at us. I love you baby!"
The pair met back in 2017 in a bar when Henson asked for a picture with The Mountain. From them on they've never looked back.
The Mountain actually went on to realise another of his life's greatest dreams recently, winning the World's Strongest Man contest and enjoying his best season to date as a strongman.
He recently revealed his daily workout routine, and it's absolutely brutal. It involves lifting the kind of weights that most of us mere mortals can only dream of picking up even once.
The difference is, he picks it up loads of times and then picks up more stuff as well. Fair play, they don't call him 'The Mountain' and 'The World's Strongest Man' for nothing, I guess.
Either way, it looks as if we'll be seeing him again in the final series of Game of Thrones, which will be hitting screens in 2019.
