Marjorie Wallace (born January 23, 1954) is an American actress, television host, model and beauty queen. In 1973, she made history as the first woman from the United States to be crowned Miss World, but just 104 days later, pageant officials announced she would be the first Miss World to have her title taken from her for having an affair. Years later, she helped launch the television program Entertainment Tonight as an original co-host.
