Hafþór “Thor” Björnsson, known as The Mountain, is famous for his remarkable strength, towering stature, and his part in Game of Thrones — but it’s his relationship with his “tiny” wife that has everyone buzzing.
Now, she addresses the one question that everyone is asking.
Hafþór Júlíus Björnsson is an Icelandic strongman and actor, widely recognized for portraying “The Mountain” in Game of Thrones. Standing at an impressive 6’9″ and weighing over 400 pounds, he ranks among the strongest men in the world, having clinched the title of World’s Strongest Man in 2018.
Describing Hafþór’s size is nearly impossible without downplaying it. His arms? They go far beyond the metaphor of tree trunks — they are truly remarkable. With biceps measuring 17 inches, a 45-inch waist, and a chest that spans 63 inches, his sheer size is astonishing. Even his fingers appear to have been crafted for strength.
In 2014, Hafþór Björnsson’s life took a significant turn. The Icelander, recognized as the third most decorated strongman in history, decided to venture into acting.
Things became serious when he was cast as Ser Gregor “The Mountain” Clegane in Season 4 of Game of Thrones, which opened up a whole new realm for him.
He starred alongside Mike Tyson.
Initially, he thought someone was playing a prank on him. When the casting team reached out while they were filming in Iceland, he found it hard to believe.
“I thought it was some kind of joke. I had no acting experience,” he remembered. “I was just a big guy competing in Strongman.”
Björnsson’s formidable presence and unforgettable role on the popular TV series have turned him into a global phenomenon. He remained with the show for several seasons, and in 2015, he was also cast in the lead role for the inaugural season of the Philadelphia Renaissance Faire. There, he portrayed ‘King Thor,’ the fierce leader of a Viking raiding party intent on seizing the city of Amman.

In 2019, the towering actor made another significant move. He starred alongside Mike Tyson in the action film Pharaoh’s War, where Tyson portrayed a former soldier with a mysterious background, leading a group of Egyptian refugees through the desert to shield them from merciless mercenaries.
Björnsson also took on a smaller role in the historical epic The Northman, sharing the screen with stars such as Alexander Skarsgård, Nicole Kidman, Ethan Hawke, and Willem Dafoe.
His ex-girlfriend feared for her safety.
Believe it or not, Hafþór Júlíus Björnsson’s personal life has been anything but smooth. The strongman-turned-actor has encountered serious allegations, with several ex-girlfriends accusing him of domestic violence.
One of his former partners, Thelma Björk Steimann (the mother of his daughter), even stated that she feared for her life during a vacation, which led her to file charges.
”I honestly thought he wouldn’t hit me when I was pregnant,” Steimann told the Icelandic newspaper Fréttablaðið.
However, the police investigation found no evidence to back her claims, and Björnsson subsequently filed a defamation lawsuit against her. He continues to assert that he has never been violent towards women.
Unfortunately, the situation escalated to the extent that Hafþór was prohibited from seeing his daughter for three years. Thankfully, things have settled down over the years, and he now regularly visits his daughter, Theresa Líf, who resides in Denmark with her mother.
Meeting Kelsey Henson.
In late 2017, a pivotal meeting in Alberta would alter Hafþór Júlíus Björnsson’s life. The towering strongman had journeyed to the Canadian province for a promotional event for Icelandic Mountain Vodka, as well as to participate in the Warwick Strongman Festival.
It was at that event that Hafþór encountered Kelsey Morgan Henson, a Canadian fitness model and waitress who immediately captured his interest. The tale goes that their connection began when Kelsey approached The Mountain to request a picture, igniting the beginning of their romance.

The couple quickly found themselves in the limelight, not just because of Hafþór’s impressive height but also due to the significant height difference between them. Kelsey measures 5 feet 2 inches, making her over a foot and a half shorter than Björnsson. What began as an intriguing sight soon evolved into something much more profound — a genuine and meaningful bond.
By August 2018, they had tied the knot, solidifying their relationship with a lovely ceremony.
“It is with immense joy that I now get to call Kelsey Morgan Henson my wife,” the actor shared alongside a picture of the couple on their wedding day.
“I get to embrace this beautiful woman through all of life’s ups and downs for the rest of our days! I’m thrilled for all the future adventures we will face together. #justmarried.”
Then, on September 26, 2020, their love story took a new turn with the birth of their son, Stormur Magni Hafþórsson, a child who would forever unite them in their shared journey.
Losing their baby daughter
One of the most heartbreaking moments in Kelsey and Hafþór’s marriage happened on November 10, 2023. The couple revealed the tragic news on Instagram that their daughter had passed away at 21 weeks of gestation.
By sharing photos of their short time with their daughter, Grace Morgan Hafþórsdóttir, Kelsey and Hafþór opened up about their devastating loss in a heartfelt Instagram post.
“It is with deep sadness that we announce the birth of our daughter, Grace Morgan Hafþórsdóttir, born Nov 8th at 21 1/2 weeks gestation. After noticing a significant decrease in movement, we learned that her heart had stopped beating,” they expressed.
“Words cannot express the depth of our sorrow from this loss, nor the joy we feel in having time with our daughter. She is truly stunning, with her blonde lashes and brows, and a sweet little smile for both mom and dad. The love we have for her is simply overwhelming,” the post went on.
“The sorrow we carry will remain with us forever, but so will our love. All our dreams and aspirations for her have been taken from us, yet I believe I will be reunited with her one day. Her spirit continues to shine through us and her siblings. We kindly ask for your understanding and respect for our privacy during this time as we mourn this unbearable loss. Thank you all for your kind words and support.”
The one question that keeps coming up
Even with his tough exterior, Thor’s gentle side — particularly regarding Kelsey and their family — is what captivates fans. Thor is thriving in his life after Game of Thrones, balancing fatherhood, fitness, and public engagements.
Kelsey, on the other hand, is the unwavering support beside him, sharing glimpses of their life on social media that showcase their love and strength.
Fans are enamored with their height difference, their down-to-earth personalities, and the touching moments they share. It’s evident that this couple, despite their physical differences, is perfectly aligned in every other aspect.
Even with their seemingly flawless romance, fans always return to one pressing question:
How does the 6’9″ giant kiss his 5’2″ wife?

During a Q&A session on Instagram, the couple finally tackled this fan-favorite question. A playful fan inquired, “Do you leap into his arms every time and wrap your legs around his waist? Please, share a picture of this impressive feat!”
Kelsey’s response was delightful, providing a funny yet practical answer. “Ah, he bends, I tiptoe. Or just say forget it, pick me up!” she replied, showcasing the fun dynamic between the two.
Despite their height difference, Thor and Kelsey continue to demonstrate that love knows no limits, blending humor, affection, and a spirit of adventure in every moment they enjoy together. It’s evident that while they may seem mismatched on paper, they are perfectly suited in every other aspect.
And now, with their kiss mystery finally unraveled, they’ve given the internet yet another reason to keep following their every move.
