Stephen Colbert is revealing he sent a note of congratulations to Byron Allen after CBS announced that "The Late Show" will be replaced by the producer's show "Comics Unleashed."

In an interview with The Hollywood Reporter published May 6, the late-night host reacted to news that "Comics Unleashed," a comedy talk show created by Allen, will take over the 11:35 p.m. time slot on CBS immediately after "The Late Show with Stephen Colbert" ends later this month.

"God bless him. I know Byron. We got to know each other last year, actually. He's fascinating. You know his history with Carson?" Colbert told the outlet, referring to the fact that Allen became the youngest comic to perform on "The Tonight Show Starring Johnny Carson" when he was 18.

"Anyway, when I found out, I wrote him the next morning and I said, 'Hey, congrats. I heard you got the time. Good for you. Wouldn't it be lovely if you could drop Mr. Carson a note?'" Colbert joked. Carson, who hosted "The Tonight Show" from 1962 to 1992, died in 2005.

But when The Hollywood Reporter asked Colbert how he feels about "The Late Show" not being replaced by a traditional late-night show, he said simply, "It's none of my business."
