AceShowbiz - "Gone with the Wind" child star Cammie King Conlon has lost her battle with lung cancer at the age of 76. The former actress, born Eleanore Cammack King, passed away on Wednesday morning, September 1 at her home in Fort Bragg, California.

Conlon landed the tragic role of Bonnie Blue Butler - the daughter of the 1939 film's lead characters Rhett Butler and Scarlett O'Hara - at the age of four. She went on to voice characters in Disney's 1942 film "Bambi", but her career ended almost as soon as it had begun after her mother pulled her out of Hollywood.

She frequently joked about how she "peaked at five", and, in a post on her blog in 2009, she wrote, "My mother decided she wanted me to have a normal childhood." Conlon later earned a degree in communications and pursued a career as a museum director and publicist.

She was married twice and is survived by her two adopted sons.
