Who are the Glosse Posse? A look at Britain’s most exclusive friendship circle

England’s aristocratic friends don’t run in a crew, a gang or a group – they’re members of a fashionable “posse,” where highbred credentials are commonplace.

This elite and well-connected circle is the “Glosse Posse,” a chummy band of Prince William and Harry’s best pals from Gloucestershire, most of whom have proud lineages that can be traced back to British dukes, earls and barons.

From their blue-blood backgrounds to their inherited lands and titles, these noble lads and lassies have been seen socializing in the most glamorous and powerful echelons of society.
