Funnyman BILL COSBY has upset rapper FAT AL by insisting he changes his moniker - because people may confuse him with the comic's FAT ALBERT cartoon character.
The teenage rap star has been forced to change his name to AL FATZ after Cosby's protests.
The rapper tells Billboard.com, "I guess he doesn't like rappers. I'm just trying to come up and Bill Cosby was hating."
