Pippa Middleton and her husband James Matthews were among some of the first A-list guests to make their way into St George's Chapel for Prince Harry and Meghan Markle's wedding day.

It's one of the first times that Pippa, 34, has been pictured in public since it was reported that she is expecting her first child with hedge-fund manager Matthews.

The Duchess of Cambridge's sister, who is said to be around four months into her pregnancy, looked radiant in a pastel-coloured floral print dress, known as The Hepburn, from London-based brand The Fold. She paired the spring-inspired design with a pale pink hat, said to be made by milliner Jess Collett, suede stilettos and a nude clutch.

According to the Sunday Express, Pippa revealed to friends and family that she is expecting her first child in April. Meanwhile, the Mail Online reports that Pippa has allegedly had her 12-week scan.

A 'friend' close to the couple also told the Sunday Express that older sister Kate 'could not have been more delighted' to learn of Pippa's news.

Harry and Markle's nuptials are taking place a year after Pippa tied the knot with Matthews on 20 May 2017. The bride wore a Giles Deacon gown for her nuptials at St Mark's Church, near her family home in Berkshire.
