"Bad Things" peaked at number four on the US Billboard Hot 100, becoming both Machine Gun Kelly and Cabello's first top ten single as solo artists, as well as the former's only top-ten hit to date.

"[4] For Fuse TV's Bianca Gracie the song shows rapper's "softer side", and highlights Cabello's "delicate vocals".

She described the song opens with Cabello "softly crooning" the hook, and MGK then comes in with a "naughty rap flow that cruises over the piano melody.

[8][9] The Recording Industry Association of America (RIAA) certified the single 5× platinum, which denotes four million units based on sales and track-equivalent on-demand streams.

MGK and Cabello can be seen enjoying late nights at diners, gathering with friends and getting into trouble all while snuggling and fighting along the way.

Stuck at the top of a building with the police hot on their trail and nowhere else to go, the pair decide to die together by committing lover's suicide.

As MGK looks longingly at Cabello, the police and their helicopters arrive to apprehend the couple and the lovers join hands and the video ends, leaving the outcome unknown.

Cabello also performed her verse as a support act at Taylor Swift's Reputation tour at Wembley Stadium, London on June 23, 2018.
