James’ collaboration with Diamond Supply Co. took place at their flagship store in LA, sponsored by Don Julio 1942. In addition, Bieber wore a casual hoodie and a big smile, while singing along to what James was spinning and giving hugs, and handshakes to the stylish party crowd. Over the years, James’ personal catch phrase and brand, “We Know The DJ” became a platform for all international and artist based DJs. Before the brand’s in-store and online launch with Diamond Supple Co, Bieber has worn the popular hoodies, hats and t-shirts of the lifestyle trend, “We Know The DJ.” DJ Tay James has been Bieber’s official DJ since his first tour, “My World” in 2010.
