Rich Homie Quan found massive success with Young Thug and Birdman in Rich Gang, but when Quan distanced himself from the collective as "Lifestyle" dominated the charts, people were surprised (and even upset, like his former bandmates). Quan had nothing but nice things to say, but you can expect the rumours to kick up again now that he's been filmed in a Miami recording studio with Lil Wayne.
As you probably know, Birdman and Young Thug are under suspicion of colluding with Jimmy Winfrey for June's attempted murder of Lil Wayne (this is separate from the drug, gun, and terroristic threats charges Thugger faces stemming from his confrontation with a mall cop). If there was any doubt of a Rich Gang reunion any time soon, the above Snapchat via Lil Wayne HQ confirms the long wait we're facing.
