Edie Falco has been tapped to guest star on three episodes of NBC's 30 Rock. With the success of the new sitcom reaching epic proportions, NBC is doing everything they can to increase the ratings in the second season. Falco is one of many celebrities who are making appearances on 30 Rock including Jerry Seinfeld.

Last season Nathan Lane, Will Arnett, Molly Shannon and Hollywood legend Elaine Stritch all made guest appearances on the sitcom. Arnett will return this season along with Rip Torn and Sherri Shepherd.
