Singleton played Caroline Appleby (formally Lillian Appleby) on the I Love Lucy series. Although Singleton was only in 10 episodes, her character was considered a neighbor and nemesis of Lucy.
LaughSpin.Com reported that although they were enemies on the show, Singleton and Lucille Ball were lifelong friends.
“There was a rivalry there but she had to be nice,” Singleton said during an Archive of American Television of the Academy of Television Arts & Sciences Foundation interview in 2005. “Lucy had to be nice to Caroline, because her husband owned the radio station.”
Fox News reported that Lucie Arnaz, Ball’s daughter, confirmed Singleton’s death in a post on her Facebook page and in an email to The Associated Press.
Although her character was short-lived in the I Love Lucy series, Singleton worked with Ball on other projects such as Here’s Lucy and The Lucy Show, LaughSpin reported.
Other shows that Singleton made an appearance on during her lifetime were: My Three Sons, All in the Family, and Perry Mason.
