After sharing that she enjoys spending time outside with her family, the royal explained, “I had a very happy childhood.It was great fun — I’m very lucky, I’ve come from a very strong family.”

She continued, “My parents were hugely dedicated to us — my siblings. I really appreciate now as a parent how much they sacrificed for us.”

Pippa married her husband, James Matthews, on May 20, 2017, and they have welcomedthree kids: son Arthur Michael William and daughters Grace Elizabeth Jane and Rose Louise Victoria.

Though the couple tend to keep their relationship and kidsout of the public eye, Pippa has occasionally spoken about juggling motherhood and her personal goals, including fitness.

“Family life and motherhood has consumed much of my spare time and unsurprisingly the challenges I thrived on have taken a back seat,” she told fitness brandHOKAin 2021. “Running and fitness still form part of my weekly routine but not to the level it was before.”

“My running has been more after babies and toddlers than crossing finish lines, which I’m fine with — for now!" Pippa added.

They are involved in charitable organizations

When her ambassadorship was announced in 2014, Pippa spoke about how she hoped to raise awareness around the importance of heart health for women and prevention of disease through healthy habits.

“I was shocked to learn that nearly three times more women die from coronary heart disease than breast cancer. I’m passionate about raising awareness amongst women of this killer disease and I look forward to working with the BHF to highlight to women the risks of heart disease and importantly, how they can reduce them,” she said in astatementat the time.

James has also gotten to work with charities he is passionate about, including Pets as Therapy, where he serves as an ambassador after experiencing firsthand the “incredible impact” of animals.

“The charity does amazing work, bringing the joy and comfort of animals to those in need, whether it’s in hospitals, nursing homes, schools or other environments," he said inhis bioon the organization’s website. “I’m so grateful to be a part of such a meaningful organisation.”

In addition, he has also helped open a center for Battersea Dogs & Cats Home and Dogs Trust Cardiff and donated a puppy to Guide Dogs, which trains service dogs. In May 2023, his dog food company, James & Ella (formerly called Ella & Co.), donated cold-pressed dog food to displaced dogs in Ukraine via K9 Rescue International.

“They are a small team who are making a big difference, and I’m honoured to have played a small part in their efforts,” hecaptioned an Instagram videoof dogs in Ukraine enjoying the food. “I’m so grateful that there are organisations going above and beyond to help support these innocent souls. Let’s continue to make a difference, one bowl of food at a time.”

“While talking about dresses with Carole and sharing ideas during lockdown for inspiration,I tried on her wedding dress and fell in love with it,” she revealed toHello!magazine. “It fitted me perfectly and was exactly what I wanted. It always troubled me that wedding dresses are only worn once, so it was amazing to give such a beautiful dress a second lease of life.”

Afterannouncing their pregnancyin the summer, the pair became first-time parents when their son, Inigo, was born in October 2023.

“No matter how prepared I thought I was …I was not prepared for the overwhelming emotionof meeting Inigo for the first time and the love for my darling Alizée as we became three,” the proud new dadwrote on Instagramwhile sharing photos of the newborn.
