Kendrick Lamar joins Imagine Dragons on Saturday Night Live to perform 'Radioactive' remix [WATCH]

Imagine Dragons were the musical guests last night on Saturday Night Live, and they brought some of their Grammy magic with them. During their performance of "Radioactive," Kendrick Lamar showed up to spit his latest addition to the track's remix.

Decked in a dark coat to conceal his identity at first, he brings an intensity to the song that makes it feel fresh despite it having grown tired from excessive radio play. Lamar then headed to Maxim's Big Game Weekend party, where he was set to perform. Imagine Dragon's returned to the stage perform "Demons."
