A former member of the Norwegian royal family claims Kevin Spacey groped his genitals during a Nobel Peace Prize party ten years ago.
Ari Behn, who divorced Princess Märtha Louise of Norway last year, revealed in an interview that he had been propositioned by the Hollywood actor.
Spacey had been hosting the annual Nobel Peace Prize concert in Oslo alongside Uma Thurman, and had sat down for a chat with the then-royal.

'We had a nice conversation, he was sat next to me,' Behn, 46, told Norwegian radio station P4.
'After five minutes, he says "Hey, let's go out and have a cigarette", and then he touched me right on the balls under the table.'
Behn, a non-smoker, says he was so surprised he just said; 'eh, maybe later?'
More than a dozen men have accused Spacey of sexual assault in the wake of an October expose by Buzzfeed which saw actor Anthony Rapp accuse Spacey of forcing himself on him when he was only 14 years old.
At least 15 young men have since come forward to say that he sexually assaulted or attempted to rape them.

Spacey will not appear on the next series of Netflix's House of Cards and has been replaced by Christopher Plummer in an upcoming drama about oil magnate Jean Paul Getty.
According to his representatives, he is seeking unspecified treatment.
Behn and Princess Märtha Louise married in May 2002 and have three children together: Maud Angelica, 13, Leah Isadora, 11, and Emma Tallulah, eight.
In August last year, the couple announced that they were divorcing, with Märtha Louise said the couple had 'grown apart'.
Alongside her royal duties, the princess has written books in which she claimed to have had contacts with angels, while Behn is a writer.
