NEW YORK — New York's hottest club in town is ... Saturday Night Live, this Sunday only. The iconic show turns 40 on Feb. 15, and we'll be treated to a three-and-a-half hour live special — starting at 7 p.m. ET on NBC (that's Sunday, not Saturday) — that has the potential to be the biggest, most-talked about episode in its four-decade history.

SNL's addictive 40th anniversary app Studio 8H at Rockefeller Center will be a packed house of current and past cast members, iconic hosts and legendary musicians. While the audience typically consists of ticket winners chosen from the general public, Sunday's seats are reserved only for SNL's A-List guests. The confirmed attendee list seems to go on for days: Tom Hanks, Amy Poehler, Tina Fey, Paul McCartney, Chris Rock, Adam Sandler, Will Ferrell, Miley Cyrus, Betty White, Dana Carvey, Chevy Chase and Steve Martin, to name a baker's dozen in a much bigger pool to come. In addition, NBC exclusively told Mashable on Friday that Sarah Silverman is the latest comedian added to the guest list cameo.
