Nicky Hilton and James Rothschild started their wedding celebrations early on Thursday with a special dinner with their nearest and dearest. The couple, who are due to tie the knot on Friday, gathered at Spencer House in St James', London for a pre-wedding party.
The bride-to-be looked stunning in a long sleeved cream lace mini dress which she paired with nude patent heels and the incredible five-carat diamond engagement ring presented to her by James when he proposed in August 2014.

Nicky arrived on the arm of her handsome fiancé, before being joined by a number of high profile guests including her sister Paris Hilton, supermodel Naomi Campbell, Chelsea Clinton and her husband Marc Mezvinsky and Petra Stunt.
Other guests to make the list were Prince Harry's ex-girlfriend Florence Brudenell-Bruce with her husband Henry Edward Hugh St George, and Holly Candy with her property developer husband Nick.
Earlier in the day Nicky enjoyed a "girls lunch" with her older sister Paris and Iraqi author Rena Sindi.

The 31-year-old wore another bridal inspired confection for her day out in the capital, choosing to wear a white lace Valentino mini dress and nude peep toe heels.
Perhaps giving a glimpse at her wedding favours, Nicky was later seen clutching biscuits in the shape of a top hat and bridal gown decorated with their names.

It looks like the blonde beauty's wedding to fiancé James is set to be the celebrity nuptials of the year. The pair have decided to marry in one of London's most glamorous settings fit for royalty, Kensington Palace.
According to New York Post's Page Six, Nicky and James will tie the knot "at the palace's Orangery in front of hundreds of guests". The Orangery is located within Kensington Gardens and is licensed for civil weddings and allows for receptions on its terrace. It is also located next door to Prince William and Kate's lavish home.
The soon-to-be married couple first met while attending the wedding of Petra Ecclestone to James Stunt back in 2011. In the summer of 2014, James popped the question to his long-term girlfriend.
