I don't think it's ok to call anyone UGLY, but it is ok to have a strong opinion about a model based either on her looks or her behavior. It's hard to decipher what's true and what's not. But gossip isn't necessarily a lie. A lot of posters do work with models - as photographers, assistants, makeup artists, hair stylists, etc. So news travels fast. Ultimately, reputations are created by a lot more then one person's gossip...
