Yet the video for Elastic Heart, which co-starred actor Shia LaBeouf, caused a stir when people criticised the singer for sexualising the then 12-year-old starlet alongside a grown man.
Sia - full name Sia Furler - suggested in her series of tweets that the question of exposing a child or teen to fame is something that should be considered and weighed by all stage parents, directors and agents.
On Thursday the enigmatic singer responded to a Guardian column which questioned Sia's use of Ziegler as an avatar of herself in her live performances and music videos.

Police also discovered a journal with a biography that was handwritten, but found no suicide note at the scene. Christopher Rogers, wrote in this report that "autopsy findings are characteristic of suicidal hanging.
The singer said this is "an important conversation" to be had, regarding young stars in the spotlight.
"Up on the stage in Sydney on Saturday, with Furler concealed and Maddie in the spotlight, it seemed that the superstar was deploying a child in a way that she herself refuses to be", Malkin wrote.
"The grown-up who has seen what fame can do and fears it has, perhaps unwittingly, handed it over to the child instead", the Guardian piece reads.
The exchange is indeed respectful, but Sia doesn't fully explain what she means, for example when she says "fame affected her differently than how it affected me" she doesn't elaborate how the experience has been different for Ziegler.

The Foreign Secretary will say the West needs to realise that hundreds of millions of Muslims are on its side in the battle against terrorism.
Posing on a beach in front of Rangitoto before the concert on Tuesday, Ziegler told her followers she was "a little bit obsessed" with New Zealand. Not to a "perfect blank slate" but to a minor who is yet to learn about, or tame, the monster'.
Malkin attended Sia's Nostalgic for the Present tour stop in Sydney, Australia, and from what she saw it raised some questions. "If that changes, we stop", she added. I thought I would do this one video and never see her again.
Maddie's performance in Chandelier has been viewed nearly 1.7 billion times since it was released in 2014.
She's also opted out of showing her face in any music videos, with most putting 15-year-old Maddie at the forefront. Things I had never dreamed of feeling insecure about.
