Prince William And Kate Middleton's Children Look So Grown Up In Rare Family Video

It's hard to believe it's been 10 years since the world tuned in to watch Prince William and Kate Middleton tie the knot. 2011 was such a different time, and so much has changed since then —headphones are now wireless, iPods are non-existent, and Kate and Wills have welcomed three children!

Now, fans are getting a glimpse into just how grown up the Royal trio is in a new, never-before-seen video shared by the family's Instagram account.

Not to be dramatic, but the world went into a literal frenzy on April 29th, 2011.

Billions of people watched as Prince Willaim married his longtime lover, Kate Middleton. Her lace, long-sleeved wedding dress completely dominated bridal trends for years. Fans were shocked to hear the Duchess had done her own makeup for the big day.

William made hearts swoon as he watched his bride walk down the aisle.

In honor of their 10-year wedding anniversary, the pair shared a series of new portraits.

"Taken this week ahead of The Duke and Duchess’ 10th wedding anniversary," the caption read. The photos, taken by photographer Chris Floyd, perfectly captured the pair's connection.

Sharing the photos to his own Instagram, Chris wrote: "I recently visited Cambridge for the first time in my life. That same day, by an astonishing coincidence, was also the day I was asked to photograph The Duke and Duchess of Cambridge for their tenth wedding anniversary."

He continued: "It was a thrill to spend some time with them at Kensington Palace, especially as The Duchess is a rather keen photographer. Happy anniversary!"

If that wasn't sweet enough, fans also got to enjoy a new, never-before-seen video of the Duke and Duchess at home with their three children — Prince George, 7, Princess Charlotte, who turns 6 on Sunday, and Prince Louis, 3.

The sweet video shows the family of five enjoy a day outdoors.

"Thank you to everyone for the kind messages on our wedding anniversary. We are enormously grateful for the 10 years of support we have received in our lives as a family," the pair captioned the post.

It's so hard to believe the pair are already parents to such big kids!

I loved being able to see this special glimpse into the family's usually private life.

What a wonderful 10 years it's been for one of our favorite Royal couples!

Cheers to many more happy years!
