This should be fun: Jerry Seinfeld is guest hosting "Live! With Regis and Kelly" on Thursday.
With Regis Philbin out this week, Seinfeld will take over co-hosting duties for one show. Not surprisingly, he’s booked for Thursday — no doubt to help hype that night’s edition of "The Marriage Ref" on NBC. Ripa recently taped a guest visit to "Ref."
Andy Richter hosted today and is back tomorrow. Wednesday, rapper Ludacris (!) will do the host chat with KR. And Friday, regular "Live" fill-in Anderson Cooper is booked to co-host.
