Cory Gunz’s reality show, Son Of A Gun is set to premiere this April. But it seems things may have already backfired. According to TMZ, MTV and executive producer Nick Cannon were served with a cease and desist from Johnny Fratto, son of mafia boss Louis Fratto. Fratto claims he has a series titled Son Of A Gun in the works and that the MTV trailer used some of his themes. Now that ain’t gangsta.
