Private couple Pippa Middleton and James Matthews made their first official public appearance at the ParaSnowBall 2017 fundraiser held at The Hurlingham Club on 4 May in London.

The bride-to-be looked radiant in an Erdem blue jacquard embellished midi dress with crystal flower embellishments. Pippa kept her brunette locks loosely curled and wore blue cage heels with cut out detailing, completing her look with a glittery box clutch. The sleeveless dressed showed off her perfectly toned arms as her fiancee James looked dapper in a tuxedo.

While the pair were spotted at Wimbledon together in 2016 and were pictured attending church at Sandringham over Christmas, it was the first time they've ever posed together at an event as a couple.

Pippa has been busy with her pre-wedding workout routine and is on a special Sirtfood diet to perfect her already svelte physique for the big day. According to E! News, Middleton was spotted leaving KX Gym in Chelsea on Wednesday (26 April) after doing an hour-and-fifteen-minute Pilates class

Pippa and James have known each other for over 10 years now and are set to get married on Saturday, 20 May, at St Mark's Church in Englefield, Berkshire. Pippa's nephew Prince George, 3, and niece Princess Charlotte, 2, will be page boy and flower girl.

Around 150 guests are expected to attend the wedding including the Duke and Duchess of Cambridge, Pippa and Kate's brother James Middleton along with girlfriend Donna Air, and Ben Fogle and Roger Federer.
