'The Real O'Neals' Sing 'O Holy Night' and 'The Greatest' Mash-Up

In a clip from Tuesday's episode, The Real O'Neals mash up the classic Christmas carol "O Holy Night" with Sia's "The Greatest"...and it was everything. 

The stars of the performance? Kenny and his new love interest, Brett.

The clip starts off with Kenny and the church choir singing the Christmas classic before Brett, played by Scream's Sean Grandillo, breaks out with Kendrick Lamar's verse from "The Greatest."

The two hit some killer notes decked in festive red robes, all while while gazing deeply into each other's eyes—all the makings for a great performance.
