More specifically, she dressed as the iconic Betty Cooper.
The sketch was hilarious, showing Halsey in the signature cardigan and pony tail.
The scene took place in a morgue, and Halsey/Betty was visiting her dead cousin (playing hilariously by Pete Davidson).
By her side was Jughead Jones, portrayed on SNL by Beck Bennet.
We cannot wait to see the sketch when it's finally available in Australia!
Halsey also got to perform “Without Me” and “Eastside,” while on the show.
