The star-studded guest list included everyone from her bf Jesse Rutherford (duh), Lil Nas X and Avril Lavigne to the Biebers, Kendall Jenner, Olivia Rodrigo, and more. Clearly, our invite got lost in the mail.

There was candy cane cake, lots of champagne and plenty of clause for celebration (sorry we had to). Check out a few more pics and videos from the party below.
