Singer Sia, 44, reveals she’s a grandmother

After sharing that she’s adopted two teenage boys, Sia has revealed another surprising fact about her personal life.

Sia has some big news.

Earlier this year, the 44-year-old singer revealed that she’d adopted two teenage boys that “were ageing out of the foster care system.”

Now, Sia’s family is growing, as she explained during an interview with Apple Music’s Zane Lowe, calling herself a “f***ing grandma.”

“My youngest son just had two babies,” said the “Chandelier” singer, per Entertainment Tonight.

While she’s happy to have the new little ones, Sia told Lowe there’s one thing she wishes were different.

“They call me ‘Nana.’ I’m trying to get them to call me ‘Lovey,’ like Kris (Jenner). I’m like, ‘Call me Lovey,’” she revealed.

The musician also opened up about what adopting two children taught her about the foster care system.

“They were ageing out of the care system. They have until they’re 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,” she said.

“It’s completely corrupt and it’s failing us. Not in my experience, in my sons’ experience. They’ve been in 18 different locations in their 18 years.”

She said there was also a bit of a learning curve taking in two practically grown young men.

“It started out as a pretty massive roller coaster. They told me one thing, I discovered another.

“I just kept really strong boundaries,” she explained.

“I would say, ‘You could do this, or you could go back to where you came from,’ which is not a nice life.”

The “Together” singer continued: “I’d say, ‘I’m doing this because I’m your mother. I love you. I have no other agenda other than the fact that I love you. I don’t want to see you in prison. I don’t want to see you as that 5 per cent that’s in prison with your history and the colour of your skin.’”

Both children have been through “trauma programs,” as Sia revealed, and one of them “recently came out.”

“He’s just blossoming and is the light of my life,” she gushed. “I love him so much.”

Meanwhile, Sia went on to say that her youngest son is still “processing” some of the trauma in his past, which Sia said she’s ”really hoping he can manage” because it took her until she was 41 to deal with her own traumas.

“I don’t want that for them, but you can’t force anyone,” explained the star.

“Trauma has to come out when you’re in a safe environment when you’re ready, psychologically ready. So, I’m just trying to do my best for them.”

Both of her sons are young black men, which Sia said helped her to recognise her own white privilege.

“I’m embarrassed that it took me to adopt two black sons to really understand what they go through on a daily basis,” confessed the powerhouse.

“There are things to do. We can actually act, and we can actually try and get justice for Breonna Taylor, and Elijah McClain, just that there’s actually, we can have an effect. We don’t have to just feel sad and guilt.”

Elsewhere in the candid chat, Sia added that she’s entering “semi-retirement” now that she’s accomplished so many of her goals.
