Over the weekend, Bieber surprised fans and popped up at The Kid Laroi's performance to sing their hit song, "Stay." He sang off to the side and sounded absolutely phenomenal!! Ugh his voice is just so beautiful. In the video below, TikToker @smilekidrauuhl captured Biebers performance and he ended up forgetting a part of the song BUT you wouldn't know the way he kept singing in tune to the songs melody. I honestly just keep watching the video because instead of stopping and having silence he came up with something clever and it matched the flow of the song. Check out the video below!
