Mendes previously teased the tune with Bieber by sharing the tracklist for Wonder, which included “Teach Me How To Love”, “Always Love You” and “Monster”, a track featuring an unannounced artist.

Mendes and Bieber then spoke about their favourite movie quotes, their new track, growing up in the limelight and more during a live stream.

In early October, Mendes didn’t deny an upcoming collab during an interview on Capital Breakfast with Roman Kemp radio show.

“Is this you trying to get me to confirm that I have a collaboration with Justin Bieber?” Mendes asked. “If I turned one down, that would be insane, considering he’s been one of my favourite artists since I was like 9-years-old.”

“Monster” drops on Nov. 20, while Wonder will be released on Dec. 4.
