The show announced other guest co-hosts to be: Goldie Hawn, Kelly Osbourne, Cyndi Lauper, Howie Mandel, Erin Andrews, D.L. Hughley and Kellie Pickler, according to The Hollywood Reporter. The show changed its format and its name for the fall relaunch, adding rotating co-hosts to try to boost ratings.

We've got a lot of fun, great things planned for the new season," said Cooper, reports THR. "I am really excited to be joined by daily co-hosts and look forward to switching to a live format, which allows us more freedom to cover topical issues as well as connect more with the viewer at home."
