'Sia's Maddie Ziegler Leaves 'Dance Moms' after Season 6

It would seem that Maddie Ziegler is officially leaving her reality TV gig, Dance Moms, for bigger and better things. According to the latest gossip news updates, the 13-year-old star of three of Sia's music video's is quitting the show that helped make her famous to continuing working with the singer as an actress in her first movie. Meanwhile, Ziegler's former reality TV tutor, Abby Lee Miller's reputation for being less than kind has the 49-year-old reality star on the defensive. Miller recently explained that she is dedicated to shaping children's talent as dancers -- not building them up into thinking they are someone special.
