Maddie Ziegler -- We’re Movin’ On Up Thanks To My Fancy Footwork

Maddie Ziegler must be cashin’ in on all those Sia videos … or at least her family is because they’re upgrading to a huge, million dollar custom-built home, complete with Maddie’s very own dance hall.

The Ziegler's 4-bedroom, 2500 sq. ft. suburban Pittsburgh pad was put on the market earlier this week and sold in just 6 hours, at the full $279,000 asking price.

Melissa, Maddie’s momager, tells TMZ the family simply outgrew their old home, and the new 7,000 sq. ft. pad is quite the step-ball-change up. Amenities include a dance studio in the basement, pool, and a closet for Maddie’s shoes. Plenty of room to also hang the 12-year-old's newest accolade -- a platinum record courtesy of Sia.
