#9: Sia
There are some celebrities out there that try their very hardest to stay out of the spotlight, even if it means altering their identities even slightly when in public. Something as simple as being able to walk down the street isn’t something some celebrities can do, so some have found a way around it.
Australian singer Sia concealed her identity for a long time, wearing a very large wig over her face during all video clips, appearances, and performances in order to protect her identity. After she had several incidents with stalkers, she decided that concealing her identity was important.
