Actress Claire Danes and American Idol winner Phillip Phillips are scheduled to appear as guests while also being on hand to fete the new co-host.
Since Philbin, 80, departed from the show in November 2011, Josh Groban, 31, Jerry O'Connell, 38, Nick Lachey, 38, Seth Meyers, 38, and even Ripa's hubby, Mark Consuelos, 41, have widely been considered contenders for the gig.
While staying mum about the others, Ripa, 41, did shoot down rumors that Consuelos, who has shared hosting duties with her before, would become a fixture at her daytime job. "No one would make me happier than Mark, but he values our marriage," the bubbly blonde said in the June issue of Vanity Fair. "He says that he doesn't see how we could stay married and both do that show."
