Aside from the Kardashian Klan, Catherine and Pippa Middleton are two of the world's most watched sisters. And though they also have a younger brother James, it's the two girls who seem to have captured the attention of royal-watchers worldwide.

Famously close even today as adults, Catherine and Pippa have relied on each other and have a sisterly relationship that many can relate to.

In 2014, Pippa revealed, "We do we have a very normal, sisterly relationship. We're very close. And, you know, we support each other and get each other's opinions and things."

"I think that's really the heart for all of us is having a really close family that we can sort of be normal with each other, treat each other normally."

From adorable English schoolgirls, to the royal bride and her bootylicious bridesmaid right up to the present day as loving wives and mothers, the Middleton sisters have grown up a lot. Catherine and her husband Prince William are proud parents to Prince George, five, Princess Charlotte, three and Prince Louis, six months while Pippa and husband James Matthews welcomed a baby boy in October.

We take a trip down memory lane and take a look at their highlights.

And we'll be keeping our eyes peeled for adorable cousin photos too!
