Many of singer D4vd's friends in the Los Angeles music scene had come to believe that Celeste Rivas Hernandez was his 19-year-old girlfriend, long before the 15-year-old's body was found dismembered in the trunk of his Tesla, which had been abandoned in the Hollywood Hills a month earlier. That's according to TMZ, which quoted music insiders who said they partied with 20-year-old D4vd, whose real name was David Anthony Burke.
