A source said: "No one was expecting royalty to drop in but it was just an incredible night."
The Duchess – née Sarah Ferguson – seemed in high spirits as she chatted to pals in a short Santa dress, novelty hat and suede knee high boots, and sang along with Prince Andrew to the band.
A source added the she looked "fantastic" in the get up after recently losing close to 42lbs.
They said: "Fergie looked fantastic and it was obvious she has a new-found confidence.
"Andrew and Fergie were singing along to the entertainment and they were dancing to the music.
"It was a real royal shindig."
Princess Beatrice also dressed up for the occasion in a Christmas pudding outfit, reports the Mirror newspaper.
Prince Andrew and the Duchess of York – who also have a 24-year-old daughter, Princess Eugenie – divorced in 1996 but have remained close friends ever since.
