Justin Bieber and Bryan Adams? Sure, we’ll take it. 

The Canadian artists performed an unlikely duet on Tuesday when Adams joined for an acoustic performance of Bieber’s star-making hit “Baby.” The spontaneous mashup — which took place at a Universal Music Group event at Mercedes-Benz Arena in Berlin — saw Adams on the guitar, and Bieber handling the vocals, including Ludacris’ verse.

Bieber’s latest single, “What Do You Mean?” recently debuted at the top of the Billboard Hot 100 chart, making him the youngest male artist to debut at No. 1. The track also set a Spotify record during its first week. 

Bieber’s next album is slated for release on Nov. 13, while Get Up, Adams’ 13th album, is due Oct. 16.
