When The Muppets return to television this fall, they're recruiting a few of their famous friends to join them.

The ABC series, which follows the behind-the-scenes action of Miss Piggy's new late-night talk show, will feature a big celebrity guest star every week.

"They are the best people in all of show business," Kermit said of the show's guest stars at the Television Critics Association summer press tour. And though Kermit couldn't reveal who all the big cameos would be, Miss Piggy did say that she would welcome Reese Witherspoon to the set of her talk show Up Late with Miss Piggy. "She jumped at the chance, oddly," Kermit said.

The Muppets will also recruit popular musical acts, including Imagine Dragons, to help bring musical elements into the new mockumentary series. "There will be very top-notch singer-songwriters, performers, bands on the show and musical acts," said writer and executive producer Bob Kushell. "But the show is not a variety show. It's not about that. ... So you'll see parts of the show with bands on [Up Late with Miss Piggy], but there won't be a full act, per se."

However, bringing all these new faces to set does come with a few challenges. "Someone tried to eat Pepe the Prawn once. He was too close to craft services and got mistaken for an appetizer," Kermit revealed. "And then there's my legs. I never go to France."

In addition to trying not to be eaten, Kermit already had his hands full while trying to executive-produce his ex-girlfriend's talk show. "Piggy and I have gone our separate ways romantically. I think it's just kind of coming out in the press now," Kermit said. "It can be tough working with your ex."

"I have no problem working with my ex, okay? It's fine," Piggy said. "Dating moi is like flying close to the sun. It was inevitable that Kermit would drop down to the ground while I stayed in the heavens."

"I thought you were going to get burned," Kermit added.

The Muppets premieres Tuesday, Sept. 22 on ABC.
