Grammy-nominated musician Sia surprised shoppers in Palm Springs Wednesday afternoon.
Viewer video shows Sia going from register to register at the Palm Springs Walmart. Viewers told News Channel 3 when asked who she was, Sia claimed her name was "Cici" and that she had just won the lottery.
Viewers said most shoppers didn't recognize the popstar, after all she is famous for her face-covering wig. One viewer said she only realized it was her after reviewing pictures.
Other viewers said they also saw Sia at the Tj Maxx on E Palm Canyon Road in Palm Springs doing the same thing.
