Buckingham Palace says there is "no record" of a meeting between the Queen and the woman at the centre of sex allegations against her son, Prince Andrew.
The woman's father has told some newspapers they met in London.
Andrew is understood to have returned home from a ski resort in Switzerland, after he was named in US court documents related to a convicted paedophile.
A palace spokesman has dismissed claims of impropriety with underage minors as "categorically untrue".
