Sources speculated that Jimmy Kimmel — who is on vacation from taping episodes of ABC’s “Jimmy Kimmel Live!” — would be among Colbert’s famous friends to appear.

Kimmel lashed out at CBS, after learning of the cancellation Thursday, writing on Instagram: “Love you, Stephen. F—k you and all your Sheldons, CBS.”

John Oliver, host of HBO’s “Last Week Tonight,” also spoke out against CBS’ decision to can Colbert.

“Late-night shows mean a lot to me, not just because I work in them, because even growing up in England, I would watch (David) Letterman’s show, which of course was Stephen’s show, and think about what a glamorous world that was,” Oliver told the Associated Press on Sunday.

“So it’s very, very, very sad news. I look forward to seeing what [Colbert is] gonna do next because that man will not stop.”

Seth Meyers, host of NBC’s “Late Nigh with Seth Meyers,” took to Instagram, writing: “For as great a comedian and host (as) he is, @stephenathome is an even better person. I’m going to miss having him on TV every night but I’m excited he can no longer use the excuse that he’s ‘too busy to hang out’ with me.”

Reps for Fallon, Kimmel, Oliver and Meyers did not respond to requests for comment.

Reps for CBS and Colbert did not comment.

CBS said that the cancellation of Colbert’s show was purely financial.
Colbert, 61, got the ax three days after he took a shot at his bosses at the Tiffany Network over its $16 million settlement with Donald Trump over a controversial “60 Minutes” interview with Kamala Harris.

The settlement comes as the network’s parent Paramount negotiates with the Trump administration regulatory approval for its $8 billion sale to independent studio Skydance.

The Post previously reported that the show clocked a staggering $40 million annual loss and Puck News reported that the show had a budget of more that a whopping $100 million a season.

“The show started to slide two years ago,” said a source with knowledge, adding that viewership declines and dips in advertising have impacted all three late-night shows.

Colbert’s show is set to end in May 2026.
