New details are emerging about the top-secret bash to celebrate Kate Middleton's last days as a single lady.

According to a report in The Daily Mail, four venues have been booked for the princess-to-be. The article also states that Kate's sister Pippa is spearheading the festivities and wants the bride-to-be to have the time of her life at a 'Dirty Dancing' themed hen party, as bachelorette parties are called in England, at home with their mum in Bucklebury, Berkshire.

"Everything is being shrouded in secrecy," a source told the newspaper. "None of the girls know where they will be going—and won’t until the actual day."
