Top-secret celebrations aren’t just for the boys. On the heels of the news that Prince Harry pulled off a covert bash for his brother Prince William, it looks like Kate Middleton and her girlfriends have done the same.
Organized by her sister Pippa, 27, Kate’s all-female fete, known as a hen party, took place behind closed doors without paparazzi intrusion.
Pippa is said to have booked four separate venues in London, including the trendy Eighty-Six restaurant, to keep guests (and perhaps the press) guessing. A Dirty Dancing-themed bash at the Middleton home in Bucklebury was said to be planned as well.
