Stephen Colbert has officially announced the final slate of guests for the concluding week of "The Late Show with Stephen Colbert," signaling the end of his decade-long tenure on CBS. The revealed lineup features a mix of high-profile celebrities and a highly anticipated mystery finale as the program prepares for its final broadcasts scheduled through May 21.

CBS and Paramount Press Express have detailed the comprehensive guest list for the final episodes of "The Late Show," which will air between May 13 and May 21. The announcement marks a significant milestone in late-night television, as Colbert prepares to vacate the host's desk at the historic Ed Sullivan Theater. The final week aims to celebrate the show’s legacy with a series of appearances from notable figures who have defined the program's run since Colbert took over the mantle in 2015.

In a moment that drew significant media attention, former host David Letterman made a return to the program. During his appearance, Letterman reportedly voiced his disapproval of CBS management regarding the decision to end Colbert's iteration of the franchise. Letterman’s return served as a bridge between the show's two eras, though his candid remarks about the network added a layer of tension to the celebratory atmosphere of the final weeks.

Transition plans for the time slot are already in motion, with media mogul Byron Allen confirmed as Colbert’s replacement. Allen recently shared that he received a personal text message from Colbert following the announcement of the succession, indicating a professional handoff between the two broadcasters. While Allen prepares to take over the late-night space, the industry remains focused on Colbert’s final performance and the "mystery finale" that producers have teased for the concluding broadcast.

Colbert has also utilized the final episodes to reflect on his time as host, sharing behind-the-scenes anecdotes with his audience. In a recent segment, he identified a specific guest whose appearance was so striking it momentarily distracted him during an interview, a rare admission for the seasoned broadcaster. As the final air date approaches, the entertainment industry anticipates a high-rated send-off for Colbert, whose program has been a staple of political satire and celebrity discourse for nearly ten years.
