Before Kate becomes Her Royal Highness, she'll get her Girls Night Out.

Sister (and maid of honor) Pippa, 27, has reportedly invited Kate's inner circle-said to include Princess Beatrice and Holly Branson, daughter of mogul Richard-to a British bachelorette party known as a hen night. To keep guests guessing, Pippa may have booked four London venues, including trendy hot spot Eighty-Six. Also reportedly on tap: a Dirty Dancing party at the family home in Bucklebury.

But don't expect the sort of antics Harry likely planned for William's rumored water-sports stag party. "Kate's very well-aware the spotlight is on her," says British society wedding planner Sarah Haywood. "The slightest slipup wouldn't go down well."

Such concerns didn't hinder Princess Diana when she and Sarah Ferguson swanned into a posh club dressed as policewomen for Fergie's 1986 hen night. Offered a cocktail, Diana is said to have replied, "Sorry, we never drink while on duty"-to giggles all around.
