Estelle Harris, who became one of TV’s most beloved characters as George Costanza’s perpetually nagging mother on Seinfeld,

died Saturday at the age of 93. Her son, Glen Harris, confirmed the actress’ death to The Hollywood Reporter.

“It is with the greatest remorse and sadness to announce that Estelle Harris has passed on this evening at 6:25pm,”

Glen said in a statement. “Her kindness, passion, sensitivity, humor,empathy and love were practically unrivaled,

and she will be terribly missed by all those who knew her.”

Estelle Costanza, became an instant fan favorite character,with her exaggerated mannerisms and

constant bickering with George and husband Frank a favorite part of the show.

“One of my favorite people has passed – my tv mama, Estelle Harris,” actor Jason Alexander,

who portrayed her son George on the series, tweeted Saturday.
