Pippa and Harry plan Kate's birthday bash

Pippa Middleton and Prince Harry are said to be planning an 80s themed party for the Duchess of Cambridge

Kate Middleton turns 30 on January 9th and professional events planner Pippa is said to be readying a birthday to remember for her sister.

The "intimate" party for close friends and family is said to will include themed dancing, cocktails and karaoke as Kate celebrates her first birthday as a Royal.

"In many ways, this is going to be Kate's last chance to let go like she did back in the old days when she and William first met", a source told Grazia magazine.

"The party has been months in the planning. Pippa and Harry have been in the thick of it, and have recruited a bunch of friends to help."

Kate is said to have asked guests to donate money to charity rather than buy her gifts but reports suggest husband Prince William is planning to buy a special oil portrait of Kate.

The Queen is also reportedly planning to give Kate a tiara from her collection to mark her landmark birthday.
