Report: Mad Men's Jon Hamm To Appear On 30 Rock

The 30 Rock guest stars just keep rolling in.

Entertainment Weekly's Michael Ausiello is reporting that Mad Men's Jon Hamm is in talks to appear in several episodes as a love interest for Liz Lemon, Tina Fey's character. Hamm and Fey crossed paths on the set of Saturday Night Live on Oct. 25, the same night Sarah Palin made her much-anticipated appearance.

So what happens when two of television's most critically acclaimed but ratings-plagued shows collide? Mad Men wrapped its second season last week; 30 Rock premieres its third season on NBC tonight.
