The royal's debut in reality television came last year when she signed up for Norway's adaptation of The Traitors

Leah Isadora Behn, the 21-year-old granddaughter of Norway's King Harald V, has revealed she will be competing on the country's equivalent of Strictly Come Dancing this autumn.

The model and influencer, who sits sixth in the Norwegian line of succession, shared the news on Instagram on Tuesday, confirming her place on the upcoming series of Skal vi danse, the Scandinavian nation's entry in the global Dancing with the Stars franchise.

The programme ranks among Norway's most popular reality television formats and will see Ms Behn paired with a professional dancer as she tackles ballroom and Latin routines.

It marks the latest foray into television for the young Royal Family member, who previously took part in Norway's version of The Traitors.

In her official portrait for the show, Ms Behn posed in a sleeveless light blue ballgown atop a disco ball, surrounded by purple lighting. "SURPRISE!!!! This fall will be crazy," she wrote in her caption.

Her mother, Princess Märtha Louise, responded to the post with the comment: "So much fun!", while her stepfather, Shaman Durek Verrett, shared the announcement on his own Instagram story. "So proud of you angel," he wrote, calling Ms Behn his "beautiful bonus daughter."

Her assigned professional dance partner, Andreas Holsthiim, also posted photographs alongside Ms Behn, captioning them: "Let the show begin."

Ms Behn subsequently joined the rest of the celebrity contestants for a group photograph ahead of the series, which is due to air later this year.

Beyond her television appearances, Ms Behn has built a varied portfolio of business ventures.

She runs her own fashion label, Hést, and has launched a gin brand, while maintaining an active social media presence with around 170,000 Instagram followers, where she regularly documents her travels.

Her debut in reality television came last year when she signed up for Forræder, Norway's adaptation of The Traitors.

She competed as a "faithful" but was "murdered" in the fifteenth episode, finishing in thirteenth place and missing out on the final.

"Mindset: gaslight, gatekeep, girlboss," she wrote at the time of announcing her casting on that show.

She is not the only royal-adjacent figure to embrace reality formats; Mike Tindall, married to Princess Anne's daughter Zara, appeared on I'm A Celebrity in 2022.

Ms Behn is the middle of three daughters born to Princess Märtha Louise and the late author Ari Behn, who died on Christmas Day 2019.

Her elder sister Maud Angelica, 23, works as an artist, while younger sibling Emma Tallulah, 17, is a competitive showjumper.

Despite being included in the line of succession, none of the three sisters holds royal titles, nor are they working members of the Norwegian Royal Family.

Their mother, the eldest child of King Harald and Queen Sonja, stepped back from official royal duties in 2022 to pursue private business interests, including work linked to alternative therapies.

She married Verrett in a three-day ceremony in the Norwegian fjords in August 2024, with all three daughters serving as bridesmaids.
