Another clip showed YBN being kicked in the face outside. He once again tried to run away after being physically attacked.
Black and YBN started dating in February of 2018 before reportedly calling it quits a couple of months later in June. The "Chopsticks" rapper later revealed on his YouTube in November that he has a son.
