Babylon 5 is probably a bit too obscure, but you don't even need to be a Taylor Swift to get that "treatment"; I'm guessing anyone playing a main character of, say, Grey's Anatomy is probably getting constantly interrupted in public (meals, gym, parks, everywhere can be fair game for shrieking fans to badger you and demand you act like the character). At least that's my experience living with someone who got such a part (although at the scale of a small country, not worldwide like Grey's).
