The cousins of Prince William and Prince Harry were spotted at a star-studded dinner last night to celebrate a new store opening.

Princess Diana’s nieces Lady Amelia Spencer, 32 , and Lady Eliza Spencer, 32, arrived at the new Aromaria store in Regent Street, London, for the lavish event.

The twins, who were accompanied by their partners Greg Mallett and Channing Millerd, wowed in stunning party dresses as they arrived at the dinner celebrations.

They were joined by a number of famous faces including Zaran Martin and Outlander actor Steven Cree.

As well as partying the night away, the sisters, whose dad Charles Spencer was Princess Diana’s brother, also enjoyed a tasty menu of Butternut squash veloute, Wagyu beef wellington, and white-tea infused panna cotta with grapefruit and white tea gel.

The event comes just over a month after Amelia and Eliza were last seen out with their sister Lady Kitty Spencer, 33, and cousin Prince William, 42.

The three sisters were invited to attend the Centrepoint Awards and Gala Dinner at The British Museum on October 16 in London, which the future King also attended.

Prince William gave a speech at the awards, with his cousins seen proudly supporting him from the sidelines.

Lady Kitty Spencer also praised the prince for his work with the homeless at the event.

She told Hello!: “I’m extremely proud of my cousin Prince William for all that he does and continues to do to support Centrepoint and the vital work they provide to homeless young people.”

It is believed that as well as maintaining a good relationship with Prince William, Amelia, Eliza and Kitty are also still in contact with Prince Harry, William’s estranged brother in America.

On one of his recent visits to the UK, it is believed Prince Harry stayed at Princess Diana’s childhood home Althorp, which is still lived in by Earl Charles Spencer, his uncle. It is also believed the prince, who quit life in the Royal Family in 2020, was also invited to spend Christmas with his Spencer relatives.

He reportedly has instead opted to spend the festive season at home in Montecito with his wife Meghan Markle, 43, and their children Prince Archie, five, and Princess Lilibet, three.
