Sia sent the star dancer in the music video of her hit song "Chandelier," Maddie Ziegler, a Hello Kitty balloon and a pink balloon bouquet as her present to her for her 12th birthday on Sept. 30, Tuesday, Bustle has learned.

Ziegler took to Instagram to post a photo of the present and to thank the Australian singer-songwriter.

"Thank you so much Sia for the birthday balloons! Love you so much also thank you to everyone for the birthday wishes yesterday," the "Dance Moms" star wrote.

At the 2014 MTV Video Music Awards in August, Sia's "Chandelier" music video starring Ziegler won Best Choreography.

"Chandelier" was also nominated for Video of the Year along with Iggy Azalea's "Fancy" featuring Charli XCX, Beyonce's "Drunk In Love" featuring Jay Z and Pharrell Williams' "Happy" but lost to Miley Cyrus' "Wrecking Ball."

Ziegler has also appeared in other music videos of several artists including Alexx Calise and Todrick Hall.

Meanwhile, Sia recently appeared on "Dancing with the Stars" with Nico & Vinz.  

On the Sept. 23 episode of "DWTS," Sia sang "Chandelier" with Ziegler and another dancer as her backup dancers while the Norwegian duo performed their hit song "Am I Wrong?" Direct Lyrics reported.

While Sia has recently collaborated with Eminem for the second time with the song "Guts Over Fear," Nico & Vinz are set to release their debut album titled "Black Star Elephant" on Oct. 14.

In a recent interview Hip Hop Wired, the duo talked about their music.

"Sometimes, when people go from rapping to singing, you're being perceived as 'You're going Pop,' or 'You selling yourself,' or whatever. Even in Norway, people never told us that because it still felt real," Nico said.  

"The music we made was us. It felt like Nico and Vinz. No one ever reacted negatively to it. It was a natural process for us to start singing more," he added.
