He has his own management business now. I'd imagine that he contracts through Strange somehow, unofficially.
I'm gonna go on record here and say that someone should jump his light skinned ass for that watch he sports. I could see that shit from across the venue. He made sure everyone was catching a glimpse of it by tucking his fucking jacket into the band of the watch and waving his hands in the air. Shit, if I were in the market for a new watch, I might have become an official hater and found his ass in the parking lot.
