It looks as though Maddie Ziegler is continuing to have the best year of her life and her career. The pint-sized dancer is scheduled to perform on ABC's hit reality competition show Dancing With The Stars on Tuesday night.

According to Star Magazine on Monday, Ziegler will be joined by Australian songstress Sia, who will be performing her summer hit, Chandelier live on the show. Ziegler will be reenacting the choreography from the video. Norwegian chart toppers Nico & Vinz will also be preforming their radio hit, Am I Wrong on the show as well.

Meanwhile, back on the dance floor, Ziegler admitted just last month that there is no onscreen rivalry between her and fellow dancer Chloe Lukasiak.

Maddie Ziegler Unhappy With Last Season Of Dance Moms

"Chloe and I are still friends," Maddie said during an interview with In Touch Weekly in August. "We just don't see each other as much when we aren't filming. She does he own thing."

Ziegler's mother Melissa Gisoni added, "To be honest with you, I don't think there's any rivalry at all. You should see Maddie and Chloe backstage. They say I love you, they pray together, it's the cutest thing. The show wants them to be at each other's throats, but they're not. They're so supportive of each other."

In addition, Gisoni says that the drama gets so intense on the show, that she and her daughters have a hard time swallowing all the "hate" that comes their way from the other dancers and their moms.

"It bugs me. I know that it's really hard to the other girls when Abby [Lee Miller] pays more attention to me," Ziegler said in the interview. "It's true, they don't get as much attention. But, I don't think it's right for the other moms to talk bad about me or behind my back. It hurts my feelings. And watching them yell at my mom, it makes me said."
