Hafþór “Thor” Björnsson, widely recognized for his towering frame, immense strength, and unforgettable role as “The Mountain” on Game of Thrones, continues to turn heads — not just for his powerful on-screen presence, but for his heartwarming relationship with his much smaller wife, Kelsey. While his massive size is constantly a topic of conversation, it’s their loving dynamic that keeps fans truly captivated. Now, Kelsey is finally addressing the one question people never stop asking.

Born and raised in Iceland, Hafþór Júlíus Björnsson earned global fame through both strength competitions and television. Towering at 6 feet 9 inches and weighing over 400 pounds, he was crowned the World’s Strongest Man in 2018. His physical stats are staggering — 17-inch biceps, a 45-inch waist, and a 63-inch chest — making him one of the most imposing figures in the world. Even his fingers seem sculpted for power.

But Hafþór’s life took a major turn in 2014 when he decided to explore the world of acting. Though already known as the third most decorated strongman in history, his leap into entertainment began unexpectedly. While filming in Iceland, he received a surprising casting call for Game of Thrones, and at first, he thought it was a prank. “I thought it was some kind of joke. I had no acting experience,” he admitted. “I was just a big dude competing in Strongman.”

But he took the opportunity and quickly made a lasting impression as Ser Gregor “The Mountain” Clegane in Season 4. His role unlocked new career paths, including a lead performance at the Philadelphia Renaissance Faire as King Thor, a fierce Viking warrior.

In 2019, Hafþór broadened his acting resume by appearing alongside boxing legend Mike Tyson in Pharaoh’s War, an action film about a mysterious soldier helping Egyptian refugees survive in the desert. He also landed a smaller role in The Northman, a historical epic featuring major stars like Alexander Skarsgård, Nicole Kidman, Ethan Hawke, and Willem Dafoe.

While Hafþór’s professional accomplishments are impressive, his personal life has had its share of turbulence. He has faced serious accusations from former partners, including allegations of domestic violence. One ex-girlfriend, Thelma Björk Steimann — the mother of his daughter — even claimed she feared for her life during a vacation. “I honestly thought he wouldn’t hit me when I was pregnant,” she told an Icelandic newspaper. However, a police investigation found no evidence supporting her claims, and Hafþór responded by filing a defamation lawsuit. He continues to maintain that he has never harmed any woman.

The emotional toll was significant. He was prevented from seeing his daughter, Theresa Líf, for three years. Thankfully, the situation has improved, and he now regularly visits her in Denmark, where she lives with her mother.

In late 2017, Hafþór’s life changed again when he traveled to Alberta, Canada, to promote Icelandic Mountain Vodka and participate in the Warwick Strongman Festival. That’s where he met Kelsey Morgan Henson, a Canadian fitness enthusiast and waitress. Their first interaction? Kelsey approached him for a photo — and that innocent moment sparked the beginning of a heartfelt romance.

The couple quickly caught public attention, not just for their sweet chemistry but because of the striking contrast in their heights. Kelsey stands at 5 feet 2 inches, making her more than 19 inches shorter than her husband. What began as a curiosity for fans blossomed into a relationship built on genuine love and mutual respect.

By August 2018, Hafþór and Kelsey were married in a beautiful ceremony. “It is with great pleasure that I now get to call Kelsey Morgan Henson my wife,” he shared on social media. “I get to hold this beautiful woman through thick and thin for the rest of our lives! I’m so excited for all the future adventures we will tackle side by side. #justmarried.”

Then, in September 2020, their family grew with the birth of their son, Stormur Magni Hafþórsson, a symbol of their deep bond and shared journey.

However, their story hasn’t been without heartbreak. On November 10, 2023, the couple revealed tragic news — their baby daughter, Grace Morgan Hafþórsdóttir, had passed away at just 21.5 weeks of gestation. In a deeply emotional Instagram post, they shared photos of their precious moments with Grace and opened up about their grief.

“It is with great sorrow that we announce the birth of our daughter, Grace Morgan Hafþórsdóttir, born Nov 8th at 21 1/2 weeks gestation. After a noticeable decrease in movement, we found out her heart had stopped beating,” they wrote. “Words cannot describe our pain of this loss or our happiness at being able to spend time with our daughter. She is absolutely beautiful, with blonde lashes and brows and a little smile for mom and dad. The love we feel for her is overwhelming.”

They continued, “The grief we feel will be with us forever but so will the love. All of our hopes and dreams for her have been taken away from us, but I know I will be with her again. Her spirit lives on through us and her siblings. We ask that you respect our privacy at this time as we grieve this unbearable loss. Thank you all for any kind words and support.”

Despite all the highs and lows, one question keeps popping up among fans: How does the 6’9″ giant manage to kiss his 5’2″ wife?

During a Q&A session on Instagram, the couple addressed the humorous but frequent inquiry. A playful fan asked, “Do you jump into his arms every time and wrap your legs around his waist? Please, post a picture of this impressive action!” Kelsey’s response was as lighthearted as it was honest: “Ah, he bends, I tiptoe. Or just say screw it, pick me up!”

Their reply perfectly captures their playful relationship and shows that love always finds a way — no matter the height difference. Hafþór and Kelsey continue to defy expectations, balancing humor, tenderness, and strength in every chapter of their journey.

While the world may see them as physically mismatched, it’s clear their emotional bond is perfectly aligned. From parenthood and public life to private heartache and shared laughter, this couple continues to win hearts around the world — not just for how they look, but for the depth of their love and resilience.
