A woman named CiCi stopped into a Walmart in Palm Springs the day before Thanksgiving, and offered to pay for everyone's groceries. She claimed she had just won the lottery, but it turns out that mystery woman was the singer/songwriter Sia! Not a lot of people recognize her face because she always wears a huge wig on stage and in videos that covers her face. Well she seems to have gained a lot of new fans from this one act of kindness!
