Maddie Ziegler

Sia doubled down on her casting decision.

Maddie was nine years old at the time of filming.

The disgraced filmmaker is currently serving a 23-year prison sentence for rape and sexual assault.

She's pretty much the luckiest 16-year-old ever.

Maddie says of her 'craziest' time on 'Dance Moms', 'I was stressed at 11 years old. Which shouldn't happen!'

Featuring Kristin Wiig, Maddie Ziegler and vocal firepower, the hour-long set has left concert-goers completely baffled.

"I’ll still keep my dancing up because I love it, but this year acting is going to be my focus."

Ziegler joins fellow judges Nigel Lythgoe, Paula Abdul and Jason Derulo.

The Abby Lee Dance Company standout has appeared on the show since its 2011 debut.
