Pippa Middleton arrives at the Royal Wedding

Pippa Middleton has arrived at the Royal Wedding, choosing a mint green dress to adorn her baby bump.

The dress is The Hepburn by The Fold, London and the shoes and clutch are by Jimmy Choo.

Pippa arrived with husband, financier James Matthews and her parents - Michael and Carole Middleton.

Prince Harry and Meghan Markle attended Pippa Middleton's wedding reception so were expected to attend.

The Duchess of Cambridge's sister is pregnant with her first child, due in October.

A friend close to the couple told the publication that Kate "could not have been more delighted" to hear the news that Pippa, 34, was expecting her first child.

"Naturally, big sister Kate and parents, Carole and Michael, were the first people she told — James aside — and they could not have been more delighted," the source said.

After becoming engaged in 2016, Pippa and Matthews wed in May 2017.

Matthews is the brother of former Made In Chelsea star Spencer Matthews, who served as best man during last year's wedding.
