The sudden development and greenlight of ABC’s upcoming Muppets series left it vaguely unclear how the gang would function in a regular mockumentary format, but Kermit and Miss Piggy dropped by TCA to offer a clue. The series will revolve around the behind-the-scenes workings of Piggy’s own late-night talk show, complete with real guests the likes of Imagine Dragons or Reese Witherspoon.

As suggested by the initial pilot presentation that won The Muppets a new series, the gang will reunite for a new ongoing series-within-the-series, revealed at the TCA press tour panel to be Up Late With Miss Piggy. Executive producer Bob Kushell was quick to point out that the series itself wouldn’t be a variety program, but rather feature said guests as the mockumentary chronicles the Muppets working on Miss Piggy’s show.

Among those first through Miss Piggy’s grinder? Imagine Dragons and Reese Witherspoon, while others will be booked as The Muppets enters production. Bad news for those among you enamored of Kermit and Miss Piggy’s pairing, however:

So reads ABC’s official description for The Muppets, airing Tuesdays this fall after a September 22 premiere:

THE MUPPETS – The Muppets return to primetime with a contemporary, documentary-style show. For the first time ever, a series will explore the Muppets’ personal lives and relationships, both at home and at work, as well as romances, breakups, achievements, disappointments, wants and desires. This is a more adult Muppet show, for “kids” of all ages.

Bill Prady (“The Big Bang Theory”) and Bob Kushell (“Anger Management”) are co-writers and executive producers. Randall Einhorn (“Wilfred”), Bill Barretta, Debbie McClellan and Kyle Laughlin are also executive producers. “The Muppets” is produced by ABC Studios and The Muppets Studio.
