"He was sitting right next to me".
Ari Behn, who was married to Princess Märtha Louise of Norway before their divorce previous year, told Norwegian radio station P4 that Spacey proposed the pair go outside. "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".
"I got more than I bargained for", he added, chuckling.
USA actor Anthony Rapp alleged Spacey made sexual advances toward him in 1986, when Spacey was aged 26 and Rapp just 14.
Kevin Spacey has now responded to the allegations made by Rapp and apologized for the misconduct in the year 1986.
Behn said that he was so surprised, he answered, "eh, maybe later".
Reacting to the allegations, Spacey posted a note on Twitter saying, "I honestly do not remember the encounter, it would have been over 30 years ago". But if I did behave then as he describes, I owe him the sincerest apology for what would have been deeply inappropriate drunken behavior, and I am sorry for the feelings he described having carried with him all these years. I have loved and had romantic encounters with men throughout my life, and I choose now to live as a gay man. "I want to deal with this honestly and openly and that starts with examining my own behavior".
