On Sunday's season finale of Life of Kylie, Kylie Jenner & her bestie Jordyn Woods cap off their trip to Peru & take their relationship to the next level in one fell swoop with a traditional commitment ceremony.

In a sneak peek at the episode, the 2 make their way into the room dressed in head-to-toe white, with Kylie, 20, carrying a baby goat & Woods, 19, holding a bouquet of roses.

As they turn to face the man presiding over the ceremony, he starts reciting the "Rites to be married" - & momager Kris Jenner starts to grow concerned.

"What? This is just a commitment ceremony," she whispers urgently to Kylie's assistant Victoria Villaroel.

It is not the first time fans have gotten an inside glimpse at Kylie's ride-or-die friendship with Woods.

During the season premiere, Woods admitted that she feels like she is in a "Full relationship" with Kylie.

The season finale of Life of Kylie airs Sunday at 9 p.m. ET on E!.
