Maddie Ziegler Is a Multi-Millionaire and the Youngest Judge in 'So You Think You Can Dance' History

At just 13 years old, Maddie Ziegler will become the youngest So You Think You Can Dance judge ever when she joins the show's upcoming kid edition, and she opened up to ET about her approach to the new gig.

"It's weird for me, because I'm not the one competing. I'm the one giving feedback to the kids," Ziegler said. "I'll just be honest and give them my feedback -- in a nice way though, because I'm not an adult, so I really can't be rude to them, and I would never be rude to them anyways."

Ziegler will be critiquing the contestants of So You Think You Can Dance: The Next Generation along with Paula Abdul, Jason Derulo and Nigel Lythgoe. Ziegler seemed especially excited to work with Abdul, as the two share a past connection. The young dancer auditioned for a part on Abdul's show, Live to Dance, in 2010, when she was only seven.

"I met her when I was little, but this is the first time I actually met her, met her," Ziegler said. "She's so sweet, and I think I'm taller than her too, which is great because I love being tall."

In fact, at 5' 3", Ziegler is three inches taller than the 5’ tall Abdul.

Ziegler's wealth has also grown as of late. She's reportedly worth $2 million after doing four videos and a Saturday Night Live appearance with Sia last year. Her earnings put her on par with Zendaya, Meghan Trainor and Gigi Hadid.
