Jerry Seinfeld, Julia Louis-Dreyfus, Jason Alexander and Michael Richards reportedly will play exaggerated versions of themselves on the show, which stars and is executive produced by "Seinfeld" co-creator Larry David.
The actors' appearances are to take place during the show's upcoming 10-week seventh season on HBO, E! News said.
This will be the first time Richards, Louis-Dreyfus, Alexander and Seinfeld have shared a soundstage since "Seinfeld" wrapped in 1998 after nine seasons.
