The Canadian musician, 24 , offered his support to David at the R&B star’s show at The Roxy on Tuesday night.

Bieber told the crowd: “This guy right here supported me from day one, came to my show in London.

David wrote on Twitter: “Thank you L.A for the amazing energy tonight for my @TS5 show. Special thanks to @justinbieber for passing through and showing so much love & for the kind words on stage.”
