Royal family member Ari Behn, who is the husband of Princess Martha Louise, claims that the incident happened 10 years ago at a function in Oslo.
“He was sitting right next to me. After five minutes, he says ‘Hey, let’s go out and have a cigarette’ — and then he takes me under the table in the middle of my balls. I got more than I bargained for," he is reported as saying in this morning's edition of The Sun newspaper.
It's certainly no laughing mater, but no doubt it probably won't be long before there's risqué jokes about the alleged incident on social media about the "crown jewels" being touched or "Norwegian Wood".
