Camila Cabello and Machine Gun Kelly perform on The Tonight Show Starring Jimmy Fallon on Nov. 23, 2016.

Cabello joins an exclusive list of artists who have led the airplay list solo & with a group.

Machine Gun Kelly and Camila Cabello crown Billboard's Pop Songs radio airplay chart with "Bad Things." The collab climbs 2-1 on the list dated Feb. 18.

The track is the first leader (and first chart entry) for rapper Kelly. Cabello reigns in her second visit as a soloist. A year ago, she reached No. 10 with Shawn Mendes on "I Know What You Did Last Summer."

As a member of Fifth Harmony (from 2012 until this past December), Cabello charted seven Pop Songs entries, including "Work From Home" (featuring Ty Dolla $ign), which led for two weeks in June 2016.

Cabello, thus, joins an elite troop of artists who've topped Pop Songs (which launched in 1992) both as a soloist and as part of a group. See Cabello's fellow group-to-solo successes below.
