Big changes are in store for NBC’s hit juggernaut “America’s Got Talent.”

Two of the show’s four judges, Julianne Hough and Gabrielle Union, won’t be returning to the show in 2020, reports Matt Donnelly in a scoop for Variety.

“An NBC spokesperson confirmed that the pair will not return for the 2020 season,” according to the story, adding “Representatives for Union and Hough did not immediately respond to requests for comment. Union and Hough had replaced longtime judges Melanie Brown (Spice Girls) and model-host Heidi Klum for the show’s 14th season.

“Executive producer and judge Simon Cowell, comedian Howie Mandel and host Terry Crews are all expected to come back to the series, said one insider familiar with the production.”

Reports Nellie Andreeva of Deadline, “Union and Hough joined ‘AGT’ in Season 14, which aired this past summer. This is only the second time in the history of the show that a judge exits after a single season. The first time was after ‘AGT‘s’ maiden cycle when original judge Brandy Norwood was replaced by Sharon Osbourne.”

The Deadline story adds, “It is unclear whether the two judges who sit alongside Cowell and Mandel on the second season of ‘AGT: The Champions,’ Heidi Klum and Alesha Dixon, will also do the mothership series in the summer.
