Pippa Middleton sparks pregnancy speculation after she is spotted with what could be a baby bump

Pippa Middleton has sparked speculation that she is expecting her third child with husband James Matthews following her appearance at the Queen’s Platinum Jubilee Party.

The 38-year-old younger sister of the Duchess of Cambridge stepped out in a lime green frock with ruched detailing across the chest for the star-studded night out at Buckingham Palace.

But some royals fans suggested the ensemble showed off a growing baby bump – while Page Six claimed Pippa is pregnant, with a source reportedly telling the outlet that the couple are ‘so happy’ and she is a ‘natural mama’.

Pippa – who attended yesterday’s event alongside her parents Carole and Michael Middleton – married former professional racing driver James, 46, in 2017 and together they already have two children, three-year-old son Arthur and one-year-old Grace.

Despite not being members of the Royal Family, the Middletons were able to bag much sought-after tickets to the concert celebrating 70 years of Her Majesty’s reign. Pippa didn’t appear to be joined by her husband.

Commenting on the photographs of Pippa from the outing, one person wrote: ‘It certainly looks like Pippa Middleton is pregnant. I didn’t want to be the first to say it and start any rumours.’

A representative for Pippa Middleton said: ‘There is no comment on the speculation.’

In keeping with her laid back style, Pippa wore her brunette locks in loose curls and kept her makeup to a minimum. She finished the ensemble with a few well-chosen pieces of jewellery, including a delicate necklace. 

Meanwhile her mother Carole opted for a crisp cream blazer and wore her hair in a fresh blow dry. Michael was typically dapper in a suit and tie. 

The Duchess of Cambridge has maintained a close relationship with her parents, brother, sister and their families, even as her role within the Royal Family has become more demanding.

The Middletons are often quiet pillars of support at high profile moments in Kate Middleton’s life, including the recent carol concert at Westminster Abbey. 

The Royal Family turned out to show their support for the Queen as she celebrates 70 years on the throne. 

While she was forced to miss out amid ongoing health struggles, she still managed to steal the show by starring opposite a computer generated Paddington Bear in a hilarious sketch to open the concert. 

The Queen brought the house down when she was joined for a cream tea by Paddington.

For the 2012 Olympic opening ceremony, James Bond famously made an appearance with the Queen – and now it was the turn of everyone’s favourite Peruvian bear – who was filmed alongside the monarch.

The Queen revealed she shares Paddington’s love of marmalade sandwiches and keeps an emergency stash in her trademark handbag.

The film was shown as the star-studded party in the shadow of Buckingham Palace began, and the Queen and her furry guest had a novel way of introducing the first act – tapping out the beat of Queen’s We Will Rock You on China teacups.

Prince George and Princess Charlotte, who earlier made a surprise visit to Cardiff Castle with their parents for a Jubilee event, were sat in the front row of the royal box for the concert alongside the Duke and Duchess of Cambridge, Prince of Wales and Duchess of Cornwall.

Members of the Royal Family joined them in the VIP seats, as did politicians including Prime Minister Boris Johnson.
