Doris Singleton | TV actress, 92

LOS ANGELES - Actress Doris Singleton, 92, who played one of Lucy and Ricky Ricardo's lesser-known neighbors on I Love Lucy, has died.

Lucie Arnaz, daughter of Lucille Ball and Desi Arnaz, confirmed the death in an e-mail to the Associated Press and in a post on her Facebook page. Ms. 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."

Ms. Singleton's character, first called Lillian Appleby and then Caroline Appleby, appeared in 10 episodes. She was Lucy's neighbor, the wife of a radio station owner.

"She was sort of Lucy's nemesis" because both had young sons, Ms. Singleton said in a 2005 interview for the Archive of American Television of the Academy of Television Arts and Sciences Foundation. "There was a rivalry there but she had to be nice, Lucy had to be nice to Caroline, because her husband owned the radio station."

Born in Brooklyn, N.Y., Ms. Singleton was a professional ballet dancer in her teens, and later became a singer and radio actress.

Ms. Singleton was married to comedy writer Charlie Isaacs for 61 years before his death in 2002. - AP
