It’s Rihanna’s Brother, Rorrey!
The guy you saw earlier is Rihanna's little brother, Rorrey Fenty! Like his big sis (whose real name is Robyn -- the Fenty's love "R" names as much as the Kardashians love their "K's"), he's a very attractive person with lots of talent, although he hasn't received as much recognition yet.
Like we said before, it's impossible for him to stay completely out of the spotlight since he is super tight with his sis Ri, but he isn't trying to use her reputation to make himself famous. Rorrey goes by the monikers GQ or Gallest, and he seems to be trying to legitimately make a name for himself. We hope the rap game works out for you, Rorrey.
