Sia's family got bigger again as just a month after adopting two teenagers, who were growing too old to be in the foster care system, the singer revealed that she has become a grandmother. She said her youngest son welcomed children of his own.

On June 30, the 44-year-old singer made an appearance on Zane Lowe's Apple Music show to reveal that her youngest son recently welcomes two babies. Sia said she is trying to get them to call her Lovey, like Kris Jenner, adding that she was immediately horrified with excitement when she was informed that the kids call her nana.

During the interview, the Cheap Thrills singer opened up about her decision to adopt two teenagers. She explained that her sons could have stayed in foster care until they turn 21, but she wanted to make sure they had a more stable life so decided to get them out of the system.

Sia said she is bored after investigating the foster system as much as she did in 2019, adding that it is failing the people. She pointed out that her sons have been sifted to 18 different locations in their 18 years. Her first experience started out as a roller coaster ride, as she kept discovering different things that didn't coincide with what they claimed.

Moreover, she continued to find more details about her son's history in the system, adding that she transformed into an Al-Anon Ninja during the process, while keeping strong boundaries. Sia said she gave her sons options to choose between doing what she said or going back to where they came from, which wasn't a good life.

Sia constantly reminded her sons that she was their mother and that her only agenda was to ensure they do not end up in prison. One of her sons recently came out, who the singer describes as the light of her life. She revealed that her sons went through complex and conditioning trauma while they were in foster care, which is why she has enrolled them in trauma programs.

Her youngest son is still recovering from the trauma, the singer admitted. According to PEOPLE, the singer is hopeful that he can manage, adding that it took her until she was 41 before she could deal with her own developmental trauma. While she doesn't want her son to go through the same lengthy recovery process, Sia said it is not possible to force anyone.

Realizing that it is easier to deal with trauma when a person is in a safe environment and is psychologically ready, Sia said she is doing her best for creating that environment for her sons.
