Christi and Cathy get heated! #DanceMoms "Dance Moms" follows Abby Lee Miller and the nation's favorite tween dancers as they take on Hollywood while new auditions, new competitions, and new studios raise the stakes. The road has not been easy for “Dance Mom’s” star Abby Lee Miller. After completing her prison sentence last year, the famed dance instructor was diagnosed with non-Hodgkin’s lymphoma. But if anything, Abby has proven she is a fighter and is not ready to hang up the dance shoes. The new season of Dance Moms follows Abby as she rebuilds her dance company while battling the after-effects of cancer that has left her confined to a wheelchair. Abby is ready to get back to her life and do what she loves most…teaching students to dance! With the goal of putting her life, health and dance studio back together, Abby returns to where it all began – the Abby Lee Dance Company in Pittsburgh.
