Why Angelina Jolie Pitt and Brad Pitt Are 'Happy as Ever' on Their Second Wedding Anniversary

Another year in the books!

Angelina Jolie Pitt and Brad Pitt “are as happy as ever” on their second wedding anniversary today, a source close to the couple tells PEOPLE.

“They really are great,” the source adds. “They’re really busy, but happy. The kids are getting so big! It’s hard to believe.”

With Pitt having wrapped his upcoming movies Allied and War Machine, and Jolie Pitt finished filming First They Killed My Father, the two are busy with post- (and pre-) production on their many projects. “It’s a very busy time for both of them, but they manage the same way they always have, as a family.” The source also notes it’s a tad easier with the kids getting older and more self-sufficient.

To celebrate the couple’s wedding anniversary, we’re taking a look back at the most memorable moments that have filled their second year as husband and wife.

By the Sea and Their Marriage

While Jolie Pitt’s directorial debut is not based on her real marriage, promoting the film last film last fall gave the couple an opportunity to reflect on their own marriage.

“It was difficult to be both inside and outside of the scenes, to be able to give directions,” she told PEOPLE in August 2015. “It was hardest [when] I was directing our fight scenes,” she added.

Finding new ways to overcome this challenge only brought the couple closer together. “I understand and appreciate his creative process and his work ethic even more than before,” she said.

Giving Back

Jolie Pitt has had a busy year as a special envoy for the United Nations’ refugee agency.

From speaking out in front of a House of Lords committee in London to advocating for victims of sexual assault in war zones back in September, to leading an honorary committee for this year’s Cambodian International Film Festival, the actress has found a variety of ways to give back to the causes closest to her heart.

She was also at the forefront of the Syrian refugee crisis this year, returning to Lebanon in the spring to meet with displaced children, some of whom she has kept in contact with since 2014.

The Kids Are Getting Big

The couple’s six kids – Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, Vivienne, 8 and Knox, 8 – are growing up fast and developing their own unique personalities.

This year, the kids have been excited to learn foreign languages. “All the kids are learning different languages,” Jolie Pitt told BBC Radio 4’s Women’s Hour. “I asked them what languages they wanted to learn and Shi is learning Khmer, which is a Cambodian language, Pax is focusing on Vietnamese, Mad has taken to German and Russian, Z is speaking French, Vivienne really wanted to learn Arabic, and Knox is learning sign language.”

While all the kids want to learn different languages, they do agree on one thing. “None of my kids want to be actors,” she revealed. “They are actually very interested in being musicians. I think they like the process of film from the outside. Mad is interested in editing. Pax loves music and deejaying.”

On Location with Mom and Dad

While the kids might not be interested in acting, their parents are still keeping their day jobs. This year, that meant a lot of traveling.

This spring, while Pitt was in London filming his upcoming World War II spy drama Allied, he was spotted meeting up with Knox and Vivienne, 8, for a special pottery-painting class in the British capitol. And earlier in the day, Pitt was seen with the twins and his eldest son, Maddox, walking around West London.

Likewise, Jolie Pitt brought some of the kids along to Cambodia while filming her upcoming multi-hyphenate effort, First They Killed My Father. The movie, which she co-wrote, produced and directed, takes place during the deadly Khmer Rouge years in Cambodia. Maddox, who was born in Cambodia, and Pax both helped out on the film, assisting with research and acting as a set photographer, respectfully.

Thailand with the Whole Family

With activities ranging from jet-skiing to swimming in the ocean to mini-golfing, the family took full advantage of their winter vacation to Thailand this year.

“The older kids went jet-skiing, and were very active. The family rented a yacht and the kids spent the day jumping off it,” a source told PEOPLE. “They spent hours swimming in the warm ocean. They played mini-golf and went shopping a few times as well.”

Even when Pax, 12, injured his right leg early into the vacation, he didn’t let it break his holiday spirit. He walked around on crutches for the rest of the week but still “looked very happy,” the source said.

New Tattoos

Jolie Pitt scored three new tattoos in her second year of marriage.

The new designs were first spotted while the actress was working on First They Killed My Father in Cambodia. They appeared to be in the yantra (or sak yant) tattoo style, a traditional Buddhist form of body art that originated in Southeast Asia. A source confirmed to PEOPLE that Jolie did indeed get three new tattoos and that they are Buddhist blessings for peace, love and a prosperous life. However, it is unclear if they were technically yantra tattoos or simply in that style.

Photos show the tattoos covering most of Jolie’s upper back in intricate geometric designs. Yantra tattoos are typical hand-etched by Buddhist monks and special ruesi practitioners, requiring meticulous skill.

Ready to Grow Old

After being together for over a decade, both Pitt and Jolie Pitt say they’re looking forward to getting older.

“Brad and I are fortunate because we see the beauty in each other’s changes,” Jolie Pitt told PEOPLE.

Speaking about how their relationship evolved while working together on By the Sea, she said, “It strengthens a relationship if you can pass those big fights and those big things where you really come head-to-head.

“As much as we can argue and fight, and we all have our challenges, at the end I say, ‘My job is to love him.’ ”

She adds, “I’m more interested in his 50-year-old self than his 40-year-old-self. And then you look forward to even more years together.”

Part of their secret has been putting the kids first. “When Angie has a day off, the first thing she does is get up and take the kids out. This is the most important ‘to do’ of the day,” Pitt told WSJ Magazine. “No matter how tired she might be, she plans outings for each and all. She has an incredible knack for inventing crazy experiences for them, something new, something fresh. I may be the bigger goof of the pair, but she invents the stage.”

While taking care of six kids can be hectic, Pitt told The Telegraph it’s all part of the fun. “[There’s] a lot of love, a lot of fighting, a lot of refereeing; a lot of teeth-brushing and spilling,” he said. “Chaos, total chaos. But so much fun.”
