The morning of Sept. 20, 2016, was a morning that would forever go down in infamy. Longtime celebrity couple Brad Pitt and Angelina Jolie announced their divorce that day, with Jolie citing "irreconcilable differences" as the reason for the split. From rumors that Pitt cheated on Jolie with co-star Marion Cotillard to child abuse allegations involving the oldest Jolie-Pitt son, Maddox, it definitely seems that the almost picture-perfect relationship Brangelina had has now turned absolutely chaotic. But for now, let's take a look back at happier times for the former couple and the many ways that they redefined relationship goals.

1. When they starred in "Mr. and Mrs. Smith" together.

The Brangelina love story began back in 2003 when they met on the set of "Mr. and Mrs. Smith." And even though it has heartbreaking to hear about Pitt's divorce from Jennifer Aniston, things worked together for the good, knowing that a brand-new romance was in full bloom.

2. When they showed off their beautiful bundles of joy to the entire world.

The couple's first child, Shiloh Nouvel, was born on May 27, 2006, and their twins, Knox Leon and Vivienne Marcheline, were born on July 12, 2008. Their first photos were revealed in the pages of People Magazine, and the Jolie-Pitts reportedly paid an estimated amount of $11 million for the photos to be released.

3. When a pregnant and glowing Jolie looked even more radiant with Pitt by her side at the Cannes Film Festival.

Two months prior to Knox and Vivienne's birth, Jolie debuted her movie, "Kung Fu Panda," at the 2008 Cannes Film Festival. Her green Max Azria Atelier dress is still one of the prettiest dresses ever seen on a pregnant woman, and her Bulgari jewels were absolutely stunning.

4. When Pitt adopted Jolie's oldest children as his own.

Pitt adopted Maddox Chivan and Zahara Marley in 2006, while Pax Thien was adopted by Pitt in 2008. Maddox and Pax were born in Cambodia and Vietnam, respectively, while Zahara was born in Ethiopia.

5. When Pitt presented Jolie with a massive Robert Procop ring.

Brangelina announced their engagement in April of 2012, and all eyes were fixated on Jolie's elaborate ring. The $250,000 sparkler from Beverly Hills jeweler Robert Procop took a year to be designed, and according to Pitt, he wanted every aspect of it to be "perfect."

6. When they finally tied the knot inside of a French chapel!

After almost a decade together, Brangelina decided to take their relationship to the next level with an intimate French wedding on Aug. 23, 2014. Jolie's wedding dress was designed by Atelier Versace, and it even included designs from every Jolie-Pitt child. Brad's tie came from one of his sons because he forgot to pack his own. Robert Procop, the same jeweler behind Jolie's engagement ring, also designed the wedding bands. It was a very magical day for everyone that was involved.

These were just a few of the fun times from Brad Pitt and Angelina Jolie's relationship. Rest in peace, Brangelina. You will truly be missed.
