See Machine Gun Kelly, Camila Cabello's Intimate 'Bad Things' on 'Fallon'

Rapper, Fifth Harmony singer also release new music video for hit

Machine Gun Kelly and Camila Cabello brought "Bad Things" to 'Fallon.'

Machine Gun Kelly and Fifth Harmony's Camila Cabello performed their lusty duet "Bad Things" on The Tonight Show on Wednesday. Kelly, wearing all black, rapped hoarse come-ons: "Let me paint the picture/ Couch by the kitchen/ Nothin' but your heels on/ Losin' our religion." Cabello, in a cloud of contrasting white, brought melismatic verve to the single's head-over-heels hook, as the band mixed hip-hop power, courtesy of a rugged drummer, with ballad drama: a weepy string section and stirring piano.

The pair also released the music video for "Bad Things" Thursday morning. In the clip, Cabello and Kelly party and cause trouble in various locations: the couple run out of a diner without paying, the rapper gets in a shoving match and someone does donuts in an empty parking lot. As Kelly puts it, "Nothing's that bad if it feels good."

Cabello is on a good streak as a duet partner. Last year, she teamed up with Shawn Mendes on "I Know What You Did Last Summer," which climbed to No. 20 on the Hot 100. By connecting with Kelly, she helped the rapper earn the biggest single of his career: "Bad Things" jumped from No. 46 to No. 28 on the Hot 100 this week.
