When Sia goes "undercover" for an act of generosity, she takes her disguises off. The 43-year-old singer, known for donning face-covering wigs, was spotted Wednesday in a Walmart in Palm Springs, Calif., fresh-faced and free with her wallet, with KESQ reporting she apparently picked up the tab for multiple fellow shoppers. When asked who she was, the Aussie performer (full name: Sia Furler) answered that her name was "Cici" and that she'd just won the lottery. Clips posted on Twitter and YouTube show the makeup-less star, wearing a long coat and her hair in a high bun, embracing customers, laughing, and posing for pictures.
Most people didn't seem to know who she really was, though others later pieced things together. "So @Sia paid for my groceries today thank you so much!!" one grateful customer posted on Twitter, along with a video showing the star bouncing from register to register to take care of business. "The heart and beautiful soul you have for paying for everyone!! I'm sorry for telling everyone once I realized who you were !! But this kindness must be acknowledged!!!" The singer, who hasn't yet publicly commented on Wednesday's sighting, also was said to have done the same thing at a local TJ Maxx, per KESQ. (Read more Sia Furler stories.)
