She will reprise her role of Verla Grubbs, a character who first appeared in the show's fictional town of Pine Valley in 1983. Verla is the long-lost daughter of Langley Wallingford, played by the late Louis Edmonds.
"Throughout her appearances on the show, Burnett played opposite legendary actresses Eileen Herlie and Ruth Warrick," the network noted. "In 1984, Burnett and Herlie teamed up with Academy Award-winning actress Elizabeth Taylor in a scene."
Burnett returned in 1995 for the 25th anniversary of the show, and also served as host of a prime-time special celebrating the daytime drama's milestone. She came back again for the show's 35th anniversary episode in 2005, and will now play Verla Grubbs one last time opposite Susan Lucci and Jill Larson, ABC said.
"It is our honor and pleasure to welcome back Carol Burnett to Pine Valley. Verla Grubbs is a beloved member of the 'All My Children' family and we look forward to reprising her character," Julie Hanan Carruthers, executive producer of the soap, said in a statement Friday.
"All My Children" is to wrap up its 41st and final season this fall.
