Personal life
Rio da Yung OG has visible facial scarring due to deep second-degree burns on the right side of his face. In an interview, he revealed that he got the scars when he was 12, as he tried to cook French fries, but was intoxicated and forgot about them, and a grease fire began. He attempted to stop the fire with water, which is dangerous because grease has a lower density than water, causing it to go up and expand the flames upwards. The burn remains because he denied getting skin graft treatment.
