Sia just dropped some huge news - she's a grandma!
She said: "I'm just immediately horrified. I'm a f**king grandma!"
Sia also recalled one emotional conversation she had with her children, in which she told them: 'I don't want to see you in prison.
"I'm trying to get them to call me "lovey" like Kris Kardashian", she explained, referencing the nickname Kris's grandchildren use for her.
That's why Sia vows to do everything she can to protect her boys, one of who recently completed his trauma program. "I love him so much". "I'm a little bit jaded now after investigating the foster system as much as I have done in the previous year", she said.
Her announcement came one month after the singer revealed that she adopted two sons that had aged out of the foster care system.
"I actually adopted two sons previous year".
"They've been in 18 different locations in their 18 years", Sia said, insisting the foster care system is "completely corrupt" and "failing" those who rely on the service. They were 18. They're both 19 now.
The prolific songwriter has yet to share any further details about her children such as their names or photos.
Sia is now isolating with her family in Los Angeles.
"They are both finding it pretty hard, one more so than the other".
'With your history and the colour of your skin, I don't want to see you as that five percent that ends up in prison for life. "They're really doing a lot of educational stuff that's good for them", she said.
In addition, Sia said that she's entering "semi-retirement" now that she's accomplished so many of her goals. "Trauma has to come out when you're in a safe environment and when you're ready, psychologically ready, so I'm just trying to do my best for them".
The Adelaide-born star is notoriously private about her personal life.
"He's just blossoming and is the light of my life", she gushed.
"I'm a little bit jaded now after investigating the foster system as much as I have done in the a year ago", she said.
"We don't have to just feel sad and guilty". I don't want that for you'.
