Virginia Giuffre was made to have sex with a mystery prince, according to recently unsealed court documents.
Ms.Giuffre claims she was a victim of late financier and convicted paedophile Jeffrey Epstein.
She has previously said she was made to have sex when she was 17 with Prince Andrew, who categorically denies any sexual contact or relationship with her.
Ms Giuffre, who is also known as Roberts, said during a 2016 deposition that she had been pressured into having sex with numerous rich and powerful men, including politicians, entrepreneurs, a scientist, a fashion designer and "another prince that I don't know his name".
When asked if she could remember "anything else" about the men, she said: "This is very hard for me and very frustrating to have to go over this. I don't recall all of the people. There was a huge amount of people that I was sent to."
There was no suggestion, however, that the mystery prince was a member of the British monarchy.
The accused men have denied the allegations.
