Conan O'Brien's replacement?

Most people know that Conan O'Brien will be taking over for Jay Leno next year, but it hasn't been completely clear as to who will take over the reigns for Mr. O'Brien's current Late Night Show.

A report on IMDB.com had this to add to the burning question:

Jimmy Fallon has been tapped to replace Conan O'Brien on NBC's Late Night when O'Brien takes over hosting duties on The Tonight Show from Jay Leno next year, Fox.com entertainment columnist Roger Friedman reported today (Thursday), saying it was "a done deal." Friedman, who cited no sources, said that NBC plans to make a formal announcement around May 11th when it presents its fall schedule to advertisers.

The choice of Fallon for "Late Night" has a certain logic to it. Fallon did at one time fill in for Letterman on the "Late Show" in 2003. He's an established comedian and is said to be a favorite of "SNL" producer Lorne Michaels, who took a chance on O'Brien for "Late Night" in 1993 and who likely will play a key role in picking O'Brien's replacement. Stay tuned for NBC's official announcement.
