Live from New York....it's all your favorite musical stars.

NBC announced today that Paul McCartney, Kanye West, Justin Timberlake, Taylor Swift and Paul Simon will be some of the musical stars for Saturday Night Live's three-hour 40th anniversary celebration on Feb. 15. 

In addition to music acts, the reunion celebration will feature icons from all eras of the program including Tina Fey, Amy Poehler, Bill Murray, Jim Carrey, Steve Martin, and Dan Aykroyd, as well as hosting veterans like Alec Baldwin, Christopher Walken and Tom Hanks. Perhaps most excitingly, Eddie Murphy will be making an appearance, which marks his first time back since he left the show in 1984. 

NBC made the announcement via the below videos, which revealed the seriously all-star (Jack Nicholson, Jerry Seinfeld, Chris Rock, just to name a few) lineup.
