What was rumored over a year ago is now finally set to happen.  Jimmy Fallon has been tapped to be Conan O’Brien’s late-night successor.

Speculation as to who would fill the 12:30 AM slot has been ongoing since NBC decided to end Jay Leno‘s run back in 2004.  With the 2009 deadline now approaching, the network is formally expected to reveal its newest golden child next month.  (I guess that means more ‘Last Calls’ for snubbed Carson Daly.)

Since leaving Saturday Night Live, Fallon has appeared in a few film projects including last year’s Factory Girl with Sienna Miller.
