Imagine Dragons were the musical guests on Saturday Night Live last night (1 February), and they were joined on stage by surprise guest Kendrick Lamar. Watch the performance below.

The collaboration came just a few days after the two acts performed together at the Grammys, previewing a brand new remix of Imagine Dragons' single 'Radioactive.' 

The new version features an entirely new verse from Lamar, who controversially lost out on the Best Rap Album award at the Grammys to Macklemore & Ryan Lewis.

The rapper appeared half way through Imagine Dragons' SNL performance, hood up, as if from nowhere, to perform his new verse.

Imagine Dragons returned later on in the show, which was hosted by comedian and actor Melissa McCarthy, to perform 'Demons.'
