It’s a Bad world for Camila Cabello…

The 19-year-old Cuban American singer and Fifth Harmony member has partnered with rapper Machine Gun Kelly for the single “Bad Things,” which dropped Friday.

Over an ominous keyboard bed, Cabello kicks the song off singing, “Am I out of my head? Am I out of my mind?/ If you only knew I like/ Don’t think that I can explain it/ What can I say, it’s complicated.”

Produced by The Futuristic (Bruno Mars, Three 6 Mafia), the instant earworm four-minute ode to dark pleasure has Cabello telling bad boy MGK “No matter what you say/ Don’t matter what you do/ I only want to do bad things to you.”

He’s down for anything, though, responding, “Nothing’s that bad if it feels good/ So you come back like I knew you would/ And we’re both wild and the night’s young.” Nails scratching backs, teeth biting lips, scars on his body… it’s complicated.

The song is available on all major digital platforms.
