Jerry Seinfeld’s “secret project” — the one he alluded to during a Reddit AMA earlier this month — is in fact a reunion of “Seinfeld,” the comedian said today.

Appearing on the “Boomer & Carton” radio show on WFAN on Thursday morning, Seinfeld answered a barrage of questions centered around a photo taken on Jan. 13 of Seinfeld with Jason Alexander, walking into the diner that served as a backdrop for many a “Seinfeld” episode.

Seinfeld said the project was not a commercial or an episode of his hit Web series “Comedians in Cars Getting Coffee,” and while he would not give away much in the way of details, he did say that Alexander was playing his George Costanza character and that other “Seinfeld” characters were involved.

He described the project as “short-ish form,” a “one-and-done” thing involving Larry David in some way that will be made available “very, very soon.”

This is not, however, the first time the “Seinfeld” gang has reunited since the show completed its run. Seinfeld, Alexander, Julia Louis-Dreyfus and Michael Richards last appeared together on David’s “Curb Your Enthusiasm” for an episode back in 2009.
