Cynthia Jean Jackson, professionally known as Jean Jennings, was born on February 13, 1957, in Fort Lauderdale, Florida, to Charles Lamar Jackson and Jean Denovan Jennings. Her mother's maiden name, Jennings, would later be adopted as her porn pseudonym. As a young girl, Jean was a cheerleader in grade school, showcasing her energetic and lively personality.
Jean's life took a dramatic turn when she ran away from home during her teenage years. She was discovered by photographer Len Camp, who introduced her to the adult entertainment industry. At the tender age of 16, Jean made her debut in the explicit hardcore movie genre. Her innocent and youthful appearance often led her to be cast as a virginal innocent, capitalizing on her nubile looks.
Over the course of her career, Jean appeared in a total of eight X-rated films before retiring from the industry in 1979. Her personal life was marked by a tumultuous marriage to character actor Joe Spinell, whom she wed in February 1977. The couple had one child together before divorcing in July 1979.
Jean's second marriage was to Roosevelt S. Booker, with whom she had a son named Alexander. She settled down in Tampa, Florida, and pursued a career as a nurse. Tragically, Jean Jennings passed away at the age of 54 on September 3, 2011, in Tampa, Florida.
