Fans of Game of Thrones may know him as the unstoppable Gregor Clegane, but off-screen, Hafþór Júlíus Björnsson—known worldwide as Thor or The Mountain—is navigating life as a husband in the spotlight. His wife, Kelsey Henson, recently answered a question from fans that has long sparked curiosity.

Björnsson, 35, is a record-breaking Icelandic strongman who made history by winning the Arnold Strongman Classic, Europe’s Strongest Man, and the World’s Strongest Man all in a single year—a feat no one else has ever achieved. Standing an eye-popping 6-foot-9, Thor’s presence is impossible to miss, whether he’s dominating in strength competitions or taking on acting roles in films like The Northman, Operation Ragnarok, and Pharaoh’s War.
But off the stage and screen, it’s his family life that has intrigued fans, especially given the striking difference in height between him and his wife. Kelsey, 34, measures just 5-foot-2, making their 19-inch gap impossible to overlook. The couple tied the knot in October 2018, with Björnsson celebrating their union on Instagram:

“It is with great pleasure that I now get to call Kelsey Morgan Henson my wife! I get to hold this beautiful woman through thick and thin for the rest of our lives! I’m so excited for all of the future adventures we will tackle side by side.”
Height difference aside, fans have been curious about the more intimate aspects of their marriage—particularly how they manage everyday gestures like kissing. During a live Instagram Q&A, one fan asked the bold question:
“How do you kiss? Do you jump into his arms each time and wrap your legs around his waist?”
Kelsey responded with humor and candor:

“Ah, he bends, I tiptoe. Or just say screw it, pick me up!”
Her lighthearted answer was met with laughter and relief from followers, who were clearly wondering the same thing. It seems love between this duo is less complicated than some might imagine.
Yet life hasn’t been without heartbreak. In 2023, the couple shared the painful loss of a daughter, opening up on Instagram about the brief but precious time they had with her. They wrote:

“After noticing a decline in her movements, we learned that her heart had stopped. The pain of losing her is indescribable, yet we are so grateful for the precious moments we had with our daughter. She was absolutely beautiful… the love we feel for her is immense. Though our grief will stay with us forever, so too will our love. Her spirit continues to live on through us and her siblings.”
Despite their tragedy, the couple continues to build their family. They share a three-year-old son, Stormur, while Björnsson is also father to a daughter, Theresa Líf, from a previous relationship. Through joy and sorrow, the Mountain and his wife demonstrate resilience, love, and a sense of humor that keeps fans fascinated.
