(NEXSTAR) — Estelle Harris, best known for her role as George Costanza’s mother on “Seinfeld” and the voice of Mrs. Potato Head in the “Toy Story” franchise, has died. She was 93.
Her representative tells Variety that Harris passed away on Saturday of natural causes.
Harris played Estelle Costanza throughout the “Seinfeld” sitcom alongside her on-screen husband, Frank Costanza, played by the late Jerry Stiller. Their son George was played by Jason Alexander. Her first appearance on the show was in an Emmy Award-winning episode from 1992, “The Contest.”
“One of my favorite people has passed – my tv mama, Estelle Harris,” Alexander posted to Twitter early Sunday morning. “The joy of playing with her and relishing her glorious laughter was a treat. I adore you, Estelle. Love to your family. Serenity now and always.”
After “Seinfeld” ended, Harris voiced Mrs. Potato Head in the 1999 Disney film “Toy Story 2.” She would later voice the character in the third and fourth installments of the franchise.

Harris appeared in many other animated projects, like “Brother Bear,” “Hercules,” and “The Wild Thornberrys,” according to Variety.
She had stopped pursuing show business when she married in the early 1950s but resumed acting in amateur groups, dinner theater and commercials as her three children grew (“I had to get out of diapers and bottles and blah-blah baby talk,” she told People). Eventually, before appearing on “Seinfeld,” Harris began appearing in guest roles on TV shows including the legal comedy “Night Court,” and in films including director Sergio Leone’s 1984 gangland epic “Once Upon a Time in America.”
According to her IMDb page, her last film role was as Mrs. Potato Head in “Toy Story 4,” which was released in 2019.
Harris is survived by her three children, three grandsons, and a great-grandson.
