Cole was born and raised in Brentwood, California, the daughter of Alice Polk Kegley, a former Ziegfeld Girl, and Carl S. Kegley, a criminal-trial attorney.

[1] She was Playboy magazine's Playmate of the Month for the May 1958 issue, with her centerfold photographed by Ron Vogel.

According to The Playmate Book, Corinne Cole used a pseudonym for her Playboy appearance because her father was considering running for Congress and she didn't want to disrupt those plans.

In 1968, Cole married Sands Hotel boss Jack Entratter; they divorced a few years later.

In 1990, she married director George Sidney, with whom she worked on the 1966 film The Swinger.
