Sia is no longer discussing her adopted children after revealing personal information

Singer Sia has said she will no longer talk about her adopted children after revealing personal information about one of them, saying she is still “learning how to be a mother”.

The Australian star, who revealed in May she adopted two 18-year-old sons last year, said it is her “job to protect my children and not blab” about what is going on in their private lives after she revealed recently one of her sons has two children of his own.

Speaking on Australian radio show The Kyle and Jackie O Show she said: “I've decided to stop talking about it.

“I made a bit of a boo-boo because they're my new children. I've only had them for a year. I'm such an open book that I forget not everyone else is.

“While I didn't get into trouble for blabbing about his [her son's] children - I was peeing, which is where I have my best thoughts, and I realised that it was not my news to share with the world.

“I instantly realised I can't talk about my children's private lives. I'm just learning how to be a mother.

“It's my job to protect my children and not blab about what's going on in their lives.”

Addressing being a grandparent on Zane Lowe's Apple Music in July, she said: “My youngest son just had two babies. I'm just immediately horrified. No, I'm cool. They call me 'Nana.' I'm trying to get them to call me 'Lovey,' like Kris (Jenner). I'm like, 'Call me Lovey.’"

Talking of her decision to adopt her sons, she added: “They were ageing out of the care system. They have until they are 21, but they were both 18 when I adopted them.

“I'm a little bit jaded now after investigating the foster system as much as I have done in the last year.”
