Doris Singleton died on Tuesday, June 26 in Los Angeles. She was 92. Doris was best known as Lucy and Ricky Ricardo’s neighbor – and Lucy’s frequent frenemy – Carolyn Appleby on ‘I Love Lucy’.

“A day of saying hasta luego to two great ladies, Nora Ephron and Doris Singleton. May they both fly swiftly heavenward and enjoy a blissful rest for jobs well done down here. They were loved and appreciated and will be missed”, Lucie Arnaz wrote on Facebook.
