Born on Jan. 9, 1982, Catherine is the oldest of Carole and Michael Middleton’s three children. She became a big sister on Sept. 6, 1983, when Pippa came along then again in 1987 when the duo became three with the addition of brother James Middleton. 

Growing up so close in age to her younger sister, Catherine and Pippa developed a strong bond. Per E! News, royal biographer Katie Nicholl wrote about their relationship in Kate: The Future Queen. She spoke with their former sports coach, Denise Allford, who shared they’d always been about working together. 

“They had such drive and were very competitive, particularly Pippa, but never against each other,” Allford told Nicholl. “They were very much a team.”

Even when the Duchess of Cambridge went away to college at the University of St. Andrews where she’d meet William, she still talked on the phone with Pippa. They reportedly kept in touch, chatting on the phone every few days. 

They remained close in their 20s 

Before Catherine officially joined the royal family in 2011 when she married William, she shared an apartment in the Chelsea neighborhood of London, England, with none other than her younger sister. Before they were both married with children, Pippa and the future Duchess of Cambridge were often spotted out around the city together. 

They sipped drinks at a charity polo match.
