"I didn’t recognise her... I blame the fact that she hid under that wig for so long."

Sia is everyone’s favourite queen of blending in, thanks to her ridiculously oversized wigs.

But turns out all those years of hiding her face has actually worked out for her.

While visiting a Walmart in Palm Springs over Thanksgiving, Sia decided to pay for everyones groceries and only a few people actually recognised her.

Sia was recently spotted at a Walmart where she paid for everyone’s groceries and other products. She also told all customers her name is Cici and that she won the lottery. 💖 pic.twitter.com/PT6zFxzq1G — The Pop Hub (@ThePopHub) November 28, 2019

She told those curious about her generosity that her name was actually CiCi. She explained that she had enough funds to do this kind deed because she had just won the lottery — and most believed the story until a few fans recognised her and blew her cover.

Running from register to register, Sia — sorry, I mean Cici — darted around the store with her bank card clearing people’s bills.

So @Sia paid for my groceries today thank you so much!! 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!!! pic.twitter.com/p7CMvBBQyP — Adri Buckles (@mexican_locaaa) November 28, 2019

Then Sia made her way down to TJ Maxx, because one store was simply not enough for our own Aussie Santa Claus.

People online praised Sia for her generosity and humility, and questioned why other celebrities don’t follow in her footsteps.

I honestly don’t understand why more rich people don’t do stuff like this, but shoutout to @Sia for doing it. https://t.co/92iE4kn41T — Franklin Leonard (@franklinleonard) November 28, 2019
