Canadian pop superstars Shawn Mendes and Justin Bieber have released their first ever collaboration, 'Monster'.

The one-take video for the track starts with Mendes walking through a misty park at night before ascending a large white cube, where he is joined by Bieber. The pair then start singing back to back as lightning strikes overhead.

In a live video in advance of the premiere, Mendes explained that the song is about "self-love", saying: "As it grew, it became more about like this idea of perfection is not real and it's like you just have to surrender and let go and be yourself and love yourself too."
