'I Love Lucy' star Doris Singleton dies

Doris Singleton, best known for her role in "I Love Lucy," has died at the age of 92.

The New York City native got her start in showbiz as a ballerina and a vocalist. A chance meeting with Lucille Ball on a radio show in 1948 led the two women to strike up a working relationship that would span decades. Ball cast Singleton in her 1950s starring vehicle, "I Love Lucy"; Singleton played the recurring role of Carolyn Appleby, Lucy and Ricky Ricardo's neighbor, known for bragging about her son, Stevie. The women worked together again several times, including on "The Lucy Show," "Here's Lucy," "Make Room for Granddaddy," and the "Bob Hope Christmas Special."

Singleton talked about her relationship with Ball in a 2005 interview with the Archive of American Television. "Lucy was very nice to me because she really liked my work. And when you did ["I Love Lucy"], if Lucy liked you -- not just Lucy but Desi [Arnaz] as well and the producers, writers, and directors -- you did the show a lot. So she had her stock company, too. If she didn't like you or you made a mistake ... you didn't come back."

Singleton said Ball was very serious on the set. "We didn't do a lot of socializing on the set," she said. "We worked very hard. It was all work and not so much play."

Ball's daughter, Lucie Arnaz, addressed the loss of Singleton, who died Tuesday in Los Angeles, in a Facebook post: "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."

In addition to her work with Ball, Singleton appeared on "All in the Family, "Adventures of Superman," "Hogan's Heroes," "My Three Sons," "The Munsters," "The Dick Van Dyke Show," "Gomer Pyle," "Marcus Welby, M.D.," "Days of Our Lives," and "Dynasty."

Singleton was predeceased by her husband of 61 years, comedy writer Charles Isaacs, who died in 2002.
