Halsey performs during Billboard Hot 100 Festival - Day 1 at Nikon at Jones Beach Theater on Aug. 22, 2015 in Wantagh, New York. 

Halsey joined BBC Radio 1 on Tuesday and delivered an impressive performance mashup of songs, including Justin Bieber's "What Do You Mean," The Weeknd's "Often" and her own "Young God."

The 20-year-old New Jersey native -- who last month released her Badlands debut album -- introduced the songs with a bit of a tease, saying, "one of which I can't stop singing, one of which is by an artist that I'm going to be joining on tour and one of which is my own."

The mashup is seamless, opening with the ticking clock and piano of "What Do You Mean" before jumping into "Often," replacing the track's heavy bass for gentle keyboard arpeggios. With ease, she transitioned back in and out of "What Do You Mean" and "Often" before transitioning to her Badlands track "Young God" off the perfectly segueing "Often" line, "In my city I’m a young god."

In case you were wondering which tease was which, Bieber's song is the one she can't stop singing and she will be touring with The Weeknd starting in late November. 

Listen here, the mashup starts at the 22:37 mark:
