As the future British Royal couple will tie the knot in April next year, reports claimed that Kate Middleton celebrated her engagement to Prince William by throwing an enormous party for herself and her girl friends.

According to some sources, the celebration took place at Clarence House earlier this month and it lasted into the early hours. Kate was joined by twelve of her private pals.

The nuptials will cost the British taxpayer around $20m, reports say.

An insider said, “When all is said and done, this wedding will likely cost the British taxpayers over $20 million.

“It will be the biggest wedding of all time, even bigger than William’s mum, Diana’s — and the price will be bigger, too.

“You really can’t compare this wedding to any other celebrity’s.

“The only other couple in the world that might even come close is if Brad Pitt and Angelina Jolie got married, but even then this will be bigger.”
