Kate Middleton celebrated her engagement to Britain’s Prince William by throwing a huge party for herself and her girlfriends, according to a tabloid report.

Sources say the bash – Which took place at Clarence House earlier this month – went on into the early hours. Kate was joined by 12 of her closet pals.

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