David Letterman will be stepping down from his hosting duties on the Late Show in just a few short weeks, but he'll be getting a serious celebrity send-off before he does. The show just announced which celebrity guests will appear in the last few weeks leading up to his final show, and viewers are in for a real treat.

According to Radio.com, the star-studded final weeks will include appearances from the following celebrities: Alec Baldwin, George Clooney, Billy Crystal, Robert Downey, Jr., Will Ferrell, Tina Fey, Michael J. Fox, Tom Hanks, Jack Hanna, Kevin James, Scarlett Johansson, Michael Keaton, Steve Martin, Bill Murray, Sarah Jessica Parker, Don Rickles, Julia Roberts, Ray Romano, Paul Rudd, Jerry Seinfeld, Martin Short, Howard Stern, John Travolta, Bruce Willis, Oprah Winfrey, Elvis Costello, Dave Matthews Band, John Mayer, Mumford and Sons and Tom Waits.

Radio.com then went on to break it down as to when said guests will be on. Tonight's show (April 13), is set to star Sarah Jessica Parker, the 2015 Masters champion Jordan Spieth and the band Asleep at the Wheel. Tomorrow (April 14) will see Billy Crystal, Julie Chen and Chris Stapleton. You can check out the rest of the week's lineup on Radio.com.

We're kind of surprised to see that there is no mention of Dave Grohl or the Foo Fighters showing up, considering they're Letterman's favorite band and he and Grohl are good friends. But in any case, the star power that will be present is huge.

Stephen Colbert is set to host the Late Show this coming fall.
