Sure, they've had their share of squabbles over the years. But that hasn't deterred Kermit and Miss Piggy from rekindling their romance. TV Guide has learned that a digitally enhanced pilot for a new version of the Muppet
is in the works at Jim Henson Studios.

"The show will have the original puppets but they'll be able to walk around," says a source close to the project. "It's going to be like the original variety show, not the cartoons that came out afterwards."

According to one Hollywood insider, Paul McCartney will appear as a celebrity guest at the 27-year reunion. "He's hilarious," says the source. " The Muppets keep asking what it's like to be a Beatle and he keeps telling them he has a new band now. They don't care at all. They just want to hear about the Beatles."

"To our knowledge, Paul McCartney is not involved in a Muppets project," the singer's publicist Paul Freundlich told TV Guide. Jim Henson Studios also denied that a new pilot is in the pipeline. However, we hear that the project is still hush-hush even in La-La Land.

"Everybody had to sign confidentiality agreements," says the source. "Nobody is allowed to say anything yet because the show is still in development."
