Well, Sia used to avoid showing her face to cameras, papparazis, etc doing anything she could because of an ideology. She believes that an artist must be famous for just only one thing: his creation. So, stuff like being beatiful or not, fat, tall, thin, really didn't matter at all. But today I checked Sia's youtube chennel and guess what I've seen? A video of her perfoming Breathe Me totally uncovered! What hapnned? Does she regret her ideology?
