Ruby Blaine was born on August 27, 1903, in Hutchinson, Kansas. When she was a child her family moved to Colorado. She loved riding horses and competed in a rodeo when she was sixteen. After winning a beauty contest she moved to New York City to become an actress. Ruby made her film debut in the 1925 drama The Midnight Girl. Although her part was small she got positive reviews. Mutual Film Company announced she would star in the The Bobbed Hair Bandit but the film was never made. Producer D.W. Griffith cast Ruby in The Sorrow Of Satan and helped her get a contract at Paramount. For a brief time she was engaged to her agent Frank Orsatti.
Ruby appeared in the movies The Great Gatsby and Bitter Apples but she never became a major star. Many magazine writers said Ruby resembled actress Norma Shearer. She hoped that dying her hair blonde would help her career. In 1928 she began working at Hal Roach's studio. She appeared in three comedy shorts including Two Tars with Laurel and Hardy. Ruby made her last film at the age of twenty-five. She married stockbroker Irving Weinberg but they divorced in 1933. Irving would later marry actress Betty Compson.
