TV’s best comedy and drama are about to collide in the most spectacular of ways.

Sources confirm that Mad Men star Jon Hamm is in advanced talks to do a multi-episode arc on 30 Rock.

Hamm, who presumably got bit by the 30 Rock bug last week while hosting Saturday Night Live, would be playing a potential love interest for Tina Fey. Word is he’s Liz’s neighbor.

Although Hamm’s deal isn’t done, it sure sounds from sources that it’s happening.
