Bergeron, who has hosted Dancing for 15 years and 28 seasons, won't return for Season 29 this fall. Andrews, Bergeron's co-host since Season 18, also won't be back. ABC said the change is part of "a new creative direction" for the long-running reality competition. “Just informed @DancingABC will be continuing without me," Bergeron tweeted this afternoon. "It’s been an incredible 15 year run and the most unexpected gift of my career. I’m grateful for that and for the lifelong friendships made. That said, now what am I supposed to do with all of these glitter masks?” Bergeron was host of Dancing with the Stars for nearly 450 episodes, from its premiere in June 2005. “Tom Bergeron will forever be part of the Dancing with the Stars family. As we embark on a new creative direction, he departs the show with our sincerest thanks and gratitude for his trademark wit and charm that helped make this show a success," ABC and BBC Studios said in a statement. "Erin will also not be returning, and we appreciate all that she brought to the ballroom. Fans have been rooting for her since she originally competed as a contestant back in 2010, and her signature sense of humor has become a hallmark of the show."
