Kate has some BIG plans for Harry’s 30th birthday bash

Prince Harry is in for a birthday bash to remember, after sis-in-law Kate invited two of his MAJOR exes!

The Duchess of Cambridge is organising a party at Kensington Palace on September 15th to celebrate Harry’s big 3-0!

And his old flames Cressida Bonas AND Chesly Davy are both on the guest list.

Kate has also invited Harry’s new love interest, charity worker Camilla Thurlow.

Harry has kept in close touch with Chelsy, who is now dating jeweller Charles Goode, since their six-year romance ended in 2010, but hasn’t been seen out with Cressida since they split in April.

Fireworks ahead?!

Kate has been overseeing arrangements for the bash with help from hubby Wills and Harry’s BFF club owner Guy Pelly.

They are planning to give one of the rooms in Kensington Palace a nightclub theme, with sexy dancers and a cocktail mixologist.

We wonder how this will go down with the rest of the Royals!
