Pippa Middleton looked radiant in an eye-catching green dress as she stepped out for the Platinum Party at the Palace in London on Saturday evening.
The 38-year-old younger sister of the Duchess of Cambridge wore her hair in loose curls, and kept her makeup to a minimum as she accessorised with a few discreet pieces of jewellery.
Pippa is married to former professional racing driver and hedge fund manager James Matthews, who is also the brother of former Made In Chelsea star, Spencer Matthews.
The socialite attended the event with her parents Carole and Michael Middleton, but there was no sign of her other half, with whom she shares children Arthur, three, and Grace, one.
They had some of the best seats in the house as a galaxy of stars including Diana Ross, Sir Rod Stewart and Andrea Bocelli took to the stage to celebrate Queen Elizabeth II’s 70-year reign.
The Queen kicked off proceedings starring alongside Paddington Bear in an adorable, pre-recorded clip.
In it, the monarch revealed that she shares than animated bear’s love of marmalade sandwiches and keeps an emergency stash in her trademark handbag.
Together, they then tapped out the beat of the song We Will Rock You on china teacups to introduce rock band Queen as the first act.
The Standard has contacted a representative for Pippa Middleton for comment.
