The special is to air on the network May 28.
"Cast members, friends and family of the beloved actress will gather on set next week to shoot a celebration of the life of their late friend," CBS said in a news release Friday. "Cooper, the Emmy Award-winning actress who portrayed Katherine Chancellor for more than 39 years, is the show's longest-running cast member."
"Jeanne Cooper was a legend and we want to give her the tribute she deserves," Angelica McDaniel, senior vice president of Daytime CBS, said in a statement. "The cast will honor their longtime friend, family member and co-worker in the greatest way possible, as we celebrate her life and vibrant spirit and share it with the audience who loved her as much as we did."
