Now that talking head Kelly Ripa is all alone on the former Live! with Regis and Kelly after television vet Regis Philbin recently retired, the network is filling the empty chair with a few guest co-hosts. The list of names includes actor Jerry O’Connell — who is currently starring in Broadway’s Seminar. Firefly’s Nathan Fillion and Glee’s Jane Lynch will be guests for the episode, which airs the day after Thanksgiving. Dancing with the Stars finalist Derek Hough co-hosts on December 5, and funnyman Jonah Hill on December 6. The Superbad actor will have a chance to speak with Sarah Jessica Parker, amongst others — which promises to be highly amusing. Singer Josh Groban takes the reins from December 7 to 9, and will perhaps talk shop with good ol’ Neil Diamond who is scheduled to appear. Will one of these fellas be filling in permanently? If so, does that mean some of you will actually start watching the show? [via Deadline]
