But the teen star did appear alongside the Lonely Island guys and many famous faces on the show this weekend for a star-studded 100th digital short.

In the video, Andy Samberg, Jorma Taccone and Bieber standing in for Akiva Schaffer celebrate the milestone by throwing a bash and well, we cant print what else they want to do. Trust us, it's gross.

Natalie Portman reprised her role as an insane, trash talking version of herself to declare, Yeah I had a baby, but Im still crazy.

Jon Hamm appeared as the shirtless sax player Sergio and Michael Bolton sang about Captain Jack Sparrow again.

Justin Timberlake colored himself badd and put a box in front of his pants, while musical guest Usher and host Will Ferrell made their first appearances.

The most glaring digital short missing from the retrospective? Lazy Sunday, t! he secon d and arguably greatest short in SNL history. Its still all about the Hamiltons, baby.
