Since she barely touches a drop of alcohol  you can rest assured Kate Middleton’s bachelorette party was a rather “dry” affair – for the bride-to-be at least!

Kate’s gregarious younger sister Pippa, ever the hostess with the mostest, is believed to have organized the bash, which was held at the house of a close friend. It had been rumored the bachelorette would take place at the Middleton family home in Bucklebury, Berkshire, but Kate was wary about photographers hanging around outside.

Believed to have been present were Olivia Bleasdale, who shared a flat with Kate and the prince at St Andrews University, and Astrid Harbord, who was once romantically linked to Prince Harry.

Alicia Fox-Pitt, a school friend from Marlborough and a fellow member of the Sisterhood dragon boat crew; Rose Astor, the wife of Prince William's close friend Hugh van Cutsem; and Alice Hadden-Paton, who is married to Mr. van Cutsem's younger brother, Nicholas, were also thought to have received an invitation. Oh, to have been a fly on the wall!

Kate’s not expected to be a teetotal as such, but suffice to say it would be frowned upon in royal circles if she ever appeared to be worse for wear. It’s rather sexist and old-fashioned, especially when you consider the number of times Prince William (and indeed his younger brother Harry) have emerged from nightclubs looking like they’ve had one too many.

While it was never known whether Diana celebrated her last night as a singleton with a “hen” night, as it is known in the U.K., she hit the headlines when she dressed up as a policewoman for Fergie’s, which took place at the exclusive London nightclub Annabel's in 1986.

With press interest in William and Kate at an all-time high with just a month to go until their wedding on April 29, it’s a miracle they managed to keep the bucks and bachelorette parties secret.
