European royal Leah Isadora Behn cast on The Traitors

Leah Isadora Behn, the daughter of Princess Märtha Louise, has been cast on the hit reality TV series Forræder, Norway’s version of the hit TV series The Traitors.

The model and influencer, who launched her own cosmetics line in 2024, will hit local screens later this year for the reality show.

Behn, 20, is the daughter of Princess Märtha Louise and the late Ari Behn who died in 2019.

Princess Märtha Louise and Behn shared three children – Maud Angelica Behn, 22, Leah Isadora Behn, 20, and Emma Tallulah Behn, 16.

Just like The Traitors, Forræder will see contestants enter a castle and attempt to outwit each other to claim the ultimate prize.

Contestants are divided into two groups, the Traitors and the Faithfuls, with the Traitors secretly chosen to eliminate them during secret missions. The Faithfuls need to try and find out who the Traitors are working in their midst.

Whichever team wins shares a grand prize.

The royal’s season will be filmed at Hvedholm Castle, a 15th-century estate.

“Mindset gaslight, gatekeep, girlboss,” she wrote on Instagram when sharing the news.

“See you this fall, this is going to be sick.”

Behn isn’t the first royal to enter the Traitor’s castle. Earlier this year Lord Ivar Mountbatten was crowned champion of the American edition of the series.
