Singer Sia has revealed she adopted her teenage sons after seeing one of them on a documentary and realising "he doesn't have anybody".
In an interview with Vogue Australia, the 'Chandelier' hitmaker admitted she was "obsessed with reality television and documentaries" - a passion which led her to motherhood.
"I watched a documentary and saw my son. I was like: 'What? Like, he doesn’t have anybody. Oh my God. I'm going to find him and I'm going to be his mummy.' And so that's what I did," she said.
The 44-year-old pop star adopted the then-18-year-old and his friend as they were aging out of the foster care system, calling becoming a mum "the best thing she's ever done".
"It's one of the hardest, but I have obviously such an overflow of love that I could definitely see myself doing it again, but not for a while," she said.
Sia said that next on her list was becoming a short-term foster parent to babies.
"The next thing I'm planning to do is foster actual infants," she said.
"Maybe [their mother] is drug-addicted and then I could help look after them until, you know, their mum can get back on the wagon or an adoptive home is found. If I can do that then I think I'll feel like I'm superhuman."
In an interview earlier this year, Sia explained that the boys she adopted had been through 18 different foster homes each throughout their lives.
"It's been really nice to be able to care from the heart for them, and I love them," she said.
