“Dance Moms” Star Maddie Ziegler Talks New Fame Working With Sia

The reality TV show “Dance Moms” may show the moms in an unflattering light, but the girls shine on stage, especially Maddie Ziegler. Filmed at a Penn Hills dance studio, Maddie now spends all day here dancing, filming and being tutored, starting with private ballet lessons at 9:30 a.m. until rehearsals wrap up at 9:30 p.m. That’s when she’s not in L.A. or New York, on shows like Saturday Night Live, Jimmy Kimmel, Disney’s “Austin and Ally” or her biggest show yet — the Grammys.
