Kate Middleton will reportedly become the first member of the British royal family to have an official baby shower. The party, which a source told The Sun was "not royal tradition", reflects the Duchess of Cambridge's desire to have a "modern life".

The shower is to be planned by Kate's younger sister, Pippa Middleton. The 31-year-old Duchess is expecting her first child with Prince William this summer. She is believed to have also secured the "blessing" of the queen, to hold a baby shower.

"It isn't royal tradition but Kate isn't a traditional royal. She is modern and wants a modern life," the source explained. "A baby shower wouldn't normally happen if you're in the Royal Family, but there is now a modern way of thinking."

The date for the baby shower has yet to be announced but it is believed it will take place at the Middleton family home in Bucklebury, Berkshire. The baby shower will also include a dummy-shaped cake, created by the Duchess' brother James Middleton, who runs his own baking firm - Cake Kit Company. Guests will be given goody bags which will include candles and gifts from high street shops Jo Malone and The White Company.

"Prince Harry, Kate and William are the Royal Family's younger generation," another source said, "It will be a great day for everyone and Kate is doing this with the blessing of the Queen."

Kate Middleton has been easing off her normally busy schedule as her due date draws closer and recently opted out of joining her William at the annual Audi Charity Polo Challenge in Chester.

However, she is expected to join the royal family at a special service to mark the 60th anniversary of the Queen's coronation, on 4 June. On 13 June, she will attend the naming ceremony of a new cruise ship in Southampton.
