Kenan Thompson Joins AGT | Guest Judge Details

Kenan Thompson Steps Into Judge’s Chair

Kenan Thompson will join the panel on NBC’s America’s Got Talent for the Quarterfinals Round 3 episode airing on September 1. He arrives to fill a vacancy left by Simon Cowell, the series creator and executive producer. Cowell is currently taking leave to undergo back surgery.

This medical procedure is a result of a major e-bike accident Cowell sustained in August 2020. That incident caused a serious spinal injury that required an extensive rehabilitation period. During his absence in the 2020 season, several guest judges filled the seat to ensure production continued without interruptions. Thompson participated as a guest judge for two live episodes during that same stage of the competition.

Historical Context of Guest Judges on AGT

Returning to the judge's chair represents a full-circle moment for the Saturday Night Live veteran. In his previous appearance, he sat alongside Heidi Klum, Howie Mandel, and Sofia Vergara. Host Terry Crews welcomed him to the desk during those 2020 live shows. The program often relies on high-profile guests to maintain continuity when primary judges are absent due to unforeseen health issues or scheduling conflicts.

At the time of his 2020 debut, Thompson spoke to the contestants about managing the pressure of the stage. He told the performers to turn their nerves into superpowers. That specific perspective as a seasoned performer offers a different critique style compared to the permanent panel. Industry watchers view these rotations as a way to keep the competition tone fresh for long-term viewers.

Production Shifts and Immediate Future

This week, the live quarterfinal episodes featured only Mel B, Howie Mandel, and Sofia Vergara. The show confirmed the news of Thompson’s upcoming appearance on their social media accounts with a post stating that a comedy legend is taking over the judge’s table. His return marks the first time this season a guest has occupied that spot.

Cowell’s recovery timeline remains private, though the network has characterized the surgery as routine. Production on the remainder of the season continues as scheduled. Viewers should expect the usual format, with Thompson providing his signature commentary to the remaining contestants on the September 1 broadcast. The long-term impact on the judging panel structure beyond this episode has not been announced by NBC at this time.
