Chelsy Davy has been spotted out and about in recent days with ex-boyfriend Prince Harry, sparking rumors of a romantic reunion.
And the glamorous blonde was in the thick of a royal posse Thursday night.
The location? None other than Prince Will's buddy Guy Pelly's club Public. A Chelsea hotspot, just off the King's Road.
Kate's sister, and maid of honor, Pippa Middleton, was there. As were Fergie's daughters, Princesses Beatrice and Eugenie.
The girls were out for a charity event, but could it have been a warm-up for Kate's bachelorette party?
Chelsy wore a midnight-blue dress and black, ankle boots.
Beatrice opted for a black skirt and silk blouse, while her sister sported an LBD (little, black dress).
Sarah Ferguson dropped off her daughters at the Chelsea club, but stopped short of joining the party.
Holly Branson, daughter of Sir Richard and a family friend of the princesses', also attended the charity event.
