Nicky Hilton looked every inch the beautiful bride at her pre-wedding dinner in London on Thursday night.

The 31-year-old socialite, who is due to wed boyfriend James Rothschild at Kensington Palace (aka, Prince William and Princess Kate‘s London home) on Friday, had all eyes on her when she stepped out in a cream minidress and beige heels.

Making the most of the summer weather, the couple posed on the steps of Spencer House in St. James’s before enjoying an intimate dinner with guests including big sister Paris Hilton, who arrived in sassy black sequined gown with daring thigh-high split.

Other guests included supermodel Naomi Campbell, Chelsea Clinton and husband Marc Mezvinsky, and Prince Harry‘s rumored ex-girlfriend Florence Brudenell-Bruce.

Earlier in the day, Hilton was spotted attending a lunch with Paris and Iraqi author Rena Sindi at the Arts Club in London’s Mayfair neighborhood. She provided a subtle clue to what her guests might have in store by carrying some wedding-themed biscuits bearing the names “James” and “Nicky.”

Lionel Ritchie is thought to be handling the wedding singing duties in a lavish wedding that joins the Hiltons to two of the world’s great banking dynasties: the Goldsmiths and the Rothschilds.
