“Dancing With the Stars” season 20 kicked off its 10-year anniversary celebration in its glittered ballroom with an introduction of the new season’s cast from returning hosts Tom Bergeron and Erin Andrews. Carrie Ann Inaba, Len Goodman, Bruno Tonioli and former pro dancer Julianne Hough each resumed their season 19 seats at the judges’ table. Season 19’s Sadie Robertson also attended the premiere, not sitting far from a new, 14-karat-gold-plated Mirror Ball trophy revealed at the start of the show.
