In a series of photos, the Reykjavik, Iceland native pierced a balloon held by Henson, extending his massive arms in celebration as the confetti cascaded down.

Björnsson donned an olive green T-shirt with black pants and black shoes, while Henson wore an all-black ensemble of a lacy top and pants in the clip.

The couple, who tied the knot in October of 2018 in Iceland, are expecting their first child together, as he has a daughter from a previous relationship.

They did the clip from amid lockdown in Björnsson’s native Iceland, where seven people have died amid the 1,675 people who’ve tested for coronavirus, according to Johns Hopkins University.

Social media posts for both Björnsson and Henson indicate they’ve focused on health, fitness and their impending parenthood amid the troubled time, which has impacted a number of his colleagues on the HBO fantasy series.

Norwegian actor Kristofer Hivju revealed in a March 16 Instagram post that he’d tested positive for the virus and had been isolating while recovering.

‘Sorry to say that I, today, have tested positive for COVID19, Corona virus,’ said the actor, who played Tormund Giantsbane on the show. ‘My family and I are self-isolating at home for as long as it takes.

‘We are in good health – I only have mild symptoms of a cold. There are people at higher risk for who this virus might be a devastating diagnosis, so I urge all of you to be extremely careful; wash your hands, keep 1.5 meters distance from others, go in quarantine; just do everything you can to stop the virus from spreading.’

He added: ‘Together we can fight this virus and avert a crisis at our hospitals. Please take care of each other, keep your distance, and stay healthy!’
