Machine Gun Kelly's collaboration with former Fifth Harmony songstress Camila Cabello has burned up the charts. The duo performed their hit "Bad Things" live on The Ellen Degeneres Show today. With their natural chemistry, the pair put quite a show on display -- Cabello with near-flawless vocals and Kelz with his usual electrifying energy. Near the end of their set, the Cleveland rapper rocked out on his guitar. 

Cabelllo stirred controversy when she left the girl group Fifth Harmony late last year following the then-budding success of "Bad Things." The song climbed up to the number 6 spot on the Billboard Hot 100 chart this week. No word yet whether she will partner with MGK for more music. However, with the rising success of their single, it wouldn't be surprising to hear more from them in the coming months.
