Joseph Garrett isn't famous. He's a gamer and video producer in his mid twenties, who leads a quiet life well away from the tabloid spotlight.

His alter-ego, though, is a superstar. Albeit one more likely to be spotted falling off a physically-impossible tower of beds in Minecraft than papped falling out of a nightclub.
