Jimmy’s hosting a talk show

Jimmy Fallon is succeeding Conan O’ Brien in the post-Tonight show slot effective in 2009, according to sources. NBC plans to announce the former Saturday Night Live star’s new gig at its upfront presentation (yes, they are having another one) on May 12.

O’ Brien is succeeding Jay Leno as host of The Tonight Show next year, and plans to move the show from Burbank, Calif. to Universal City, Calif.
