DaBaby got caught riding dirty in the fancy part of town.

The Charlotte rapper was shopping on Beverly Hills's famed Rodeo Drive when the cops pulled over his suburban and found a gun.

DaBaby and three other men had just been shopping at Moncler.  Somebody in the store had called the cops and said DaBaby and his crew had been armed during their visit. 

DaBaby was the only person arrested initially, although the cops are saying more arrests are coming.

DaBaby's charge is carrying a loaded firearm, which is a misdemeanor.
