Halsey just checked off one HUGE thing on her bucket list. Starting off 2018 by performing as the musical guest on SNL, she's just conquered something that most artists hope to do at some point in their career. The episode was hosted by actor Sam Rockwell.
Halsey first took the stage to perform her hit "Bad At Love" & was later joined by her boyfriend G-Eazy, to perform the duet "Him & I".
