Doris Singleton "I Love Lucy"

Actress Doris Singleton, who played Lucy and Ricky Ricardo's neighbor on "I Love Lucy," has died. She was 92.

Lucie Arnaz, daughter of Lucille Ball and Desi Arnaz, confirmed the death in a post on her Facebook page. Singleton died Tuesday, the same day as writer-director Nora Ephron, and Arnaz acknowledged them both in her post, writing, "They were loved and appreciated and will be missed."

Singleton appeared on dozens of TV shows in the 1950s, 60s and 70s, including "Perry Mason," "My Three Sons," "All in the Family" and "Hogan's Heroes."

She was the last surviving adult member of the "I Love Lucy" show.
