Kelly Ripa Lands Derek Hough, Jonah Hill, Jerry O'Connell, and Josh Groban as Fill-in Co-Hosts

Hough and Hill co-hosting for first time

Derek Hough, Jonah Hill, Jerry O'Connell and Josh Groban will try to fill Regis Philban's big, well-worn shoes when they fill in as Kelly Ripa's cohost's on the recently renamed "Live! With Kelly" in the coming weeks.

"Dancing With the Stars" professional Hough, who will co-host Dec. 5, and Hill, who will join Ripa the next day, are co-hosting for the first time.

O'Connell, sitting in this Friday, and Josh Groban, settling in Dec. 7-9, are returning to the show.

Philban signed off Friday after nearly three decades with the show. Ripa's first guest co-host this week was Jerry Seinfeld.
