Time to take a walk down memory lane to the fated day of September 21 — aka the day Teen Mom 2's Kailyn Lowry got married to her husband, Javi Marroquin. Sob, we're tearing up just thinking about it!

Kailyn and Javi's wedding was a long time coming (actually, they had been legally married for a year at the time of their soiree), and it was an emotional day for everyone involved — including their extended families! Javi is extremely close to his parents and brother (who were in attendance), but Kailyn made the bold decision not to invite her mom or her dad, both of whom she has notoriously strained relationships with.

So, who did Kailyn have sitting on her side of the aisle? That would be her fleet of sister-friends from Texas! Kailyn has three half-sisters named Kaylie, Mikaila, and Carli, all of whom she's pretty close to. This blushing bride formed a connection with her siblings when she visited them in Texas during Teen Mom 2's third season, and they've been joint at the hips ever since.

You better believe these ladies showed up to watch their sister walk down the aisle at a local aquarium in Camden, New Jersey, and Kailyn recently posted a flash-back photo of their wedding day reunion.

"My beautiful sisters and the aunt who should have been mom!" Kailyn wrote on Instagram along with the picture. "Traveled all the way from Texas to be there for me!"

Cue happy tears. While it's too bad that neither of Kailyn's parents witnessed this momentous event in their daughter's life, it's wonderful that her sisters were able to attend the wedding to support their BFF. Kailyn is one lucky lady!
