Camila Cabello’s Duet With Machine Gun Kelly Will Launch You Back Into The ’90s

Fifth Harmony, meet Fastball

Camila Cabello's latest solo feature is here in a new duet with Machine Gun Kelly, and if you're getting major déjà vu from the vocal melody, you're not alone.

The pair's new single "Bad Things" interpolates an 18-year-old song, the 1998 hit "Out of My Head" by Fastball. Cabello's part even keeps some of the original lyrics, though they sound pretty different on her extra-smooth pipes between MGK's verses.

Raise your hand if you just got flashbacks to a way, way more innocent time.
