Sia has revealed that she adopted two teenage boys who were aging out of foster care last year.
The singer made the surprising revelation during an interview with GQ when she explained that she had become a mom, however, until now, no one realized that she did so through an adoption program.
Sia went undercover to buy groceries for holiday shoppers at Walmart:

The 'Chandelier' hitmaker told Sirius XM Radio: "I actually adopted two sons last year. They were both 18 - they're both 19 years old now. They were aging out of the foster care system. Yeah, and I love them."
The 44-year-old Australian added that her sons have found adjusting to life during the coronavirus pandemic challenging.
"They are both finding it pretty difficult, one more so than the other," she said.
"But they're both doing things that are really good for them right now, that are really helpful. They're really doing a lot of educational stuff that's good for them.''
The singer did not provide any more information about the two teenagers, which is very much true to form as she has made no secret of her wish to remain largely out of the public eye.
After splitting from filmmaker Erik Lang in 2016, Sia vowed to stay single forever.
However, that hasn't stopped the singer from propositioning people for casual sex, and she also revealed in the GQ interview that she offered a fling to her longtime producer Diplo.
She said: "Hey, listen, you're like one of five people that I'm sexually attracted to, and now that I've decided to be single for the rest of my life and I just adopted a son, I don't have time for a relationship... If you're interested in some no-strings sex, then hit me up."
No one knows if Diplo took the 44-year-old up on her offer.
