They're majorly hated por people who don't care enough to at least find out who they are? I mean, Niall is actually a really aleatório idiot who has a laughing fit every other segundo and Robert hates Twilight mais than any other person on the planet =)
Robert is the an actor who played as Edward Cullen from Twilight and Cedric Diggory from Harry Potter. Niall Horan is a singer and he is in the band One Direction.
