The video, which has been viewed by 3.1 million people, shows the ‘Baby’ singer on stage with a drink in his hand as he belted out the track to his adoring fans.
A guitarist can be heard in the background alongside the two vocalists, with Bieber attempted the lyrics before adding “Cause I don’t remember the words and that’s crazy”.
Despite the blunder, and a chuckling security guard in the background, the performance received a positive response across TikTok:
One user wrote: “His vocals are everything guys”
Another wrote: “ You can barely notice he forgot the lyrics because of how perfect he handled it”
A third penned: “Even messing up and forgetting he made it sound soo good”
