Billie Eilish's debut record WHEN WE ALL FALL ASLEEP, WHERE DO WE GO, kicks off with the trancey, Invisalign-chucking "bad guy." It's currently the biggest hit on the album, and today, she's doubling down on that by releasing a new version with guest vocals from Justin Bieber. It's actually a pretty huge deal because, as the single art shows, Eilish was a massive Bieber fan in her tween years. In her recent Over/Under interview with Pitchfork, she credits him, Avril Lavigne, Childish Gambino, Lana Del Rey and Tyler the Creator as her biggest influences.
