In our minds, Angelina Jolie and Brad Pitt’s six children are still… small.

So last year when we saw five of the six Jolie-Pitt kids on the red carpet for the premiere of Angelina’s movie Maleficent: Mistress of Evil, it’s safe to say we were a little shooketh.

Pax, 16, Zahara, 15, Shiloh, 13 and 11-year-old twins Vivienne and Knox all joined Angelina on the red carpet and well, doesn’t time fly.

Maddox, Zahara and Pax were adopted from orphanages in Cambodia, Ethiopia and Vietnam respectively, and Shiloh, Vivienne and Knox are Angelina and Brad's biological children.

Of course, Jolie and Pitt called quits on their relationship in 2016 after 12 years together. Late last year, they reached an agreement after a two-year custody battle. Jolie had been seeking primary custody of all six children, but a statement about the agreement did not specify details.

Here's the trailer for Maleficent: Mistress of Evil. Post continues after video.

The Jolie-Pitt kids aren't often seen in public, but we managed to see 18-year-old Maddox, the couple's eldest child, checking out his new university in South Korea.

According to People, Maddox was accepted to multiple South Korean universities but chose Yonsei, where he's started studying biochemistry.

It's not a huge surprise, given that in November Jolie and Maddox were spotted visiting school campuses in Seoul, while Jolie was in South Korea on an official visit as the United Nations High Commissioner for Refugee Special Envoy.

Jolie, 44, previously told People she was "nothing but proud" of her eldest child.

"I look forward to all he will do," the actress added.

In her Elle cover story last year, Jolie again praised her children.

"I could not be prouder of my sons for the men they are becoming, the way they respect their sisters and are respected by them," she wrote.

Jolie, who is a contributing editor for Time magazine, wrote an article earlier this week for International Women's Day. As part of it, she shared how both of her daughters underwent surgery recently.

She wrote, "I have spent the last two months in and out of surgeries with my eldest daughter, and days ago watched her younger sister go under the knife for a hip surgery."

"I have watched my daughters care for one another. My youngest daughter studied the nurses with her sister and then assisted the next time. I saw how all my girls so easily stopped everything and put each other first and felt the joy of being of service to those they love."

She also explained how her sons were there for their sisters, "Their brothers were there for them, supportive and sweet."

Seeing the kids all together got us feeling nostalgic, so here's a look at how they've grown over the years.

Yep, they grow up so fast.
