Arlene Dahl was born August 11, 1928 in Minneapolis, Minnesota and is of Norwegian descent. She is the mother of actor Lorenzo Lamas.
In 1946, Dahl was voted the Rheingold Beer Girl. She began her acting career in 1947, at the age of 19. Her acting career gradually picked up momentum reaching the peak of her popularity and success in the 1950's. Some her best films include Reign of Terror (1949), Three Little Words (1950), Woman's World (1954), Slightly Scarlet (1956), and Journey to the Center of the Earth (1959).
Arlene met actor Lex Barker in the early 1950's, and on April 16, 1951, Dahl and Barker wed. A year later she and Barker divorced, and she would go on to marry another matinee idol Fernando Lamas. In 1958, Dahl and Lamas had their only son, Lorenzo Lamas. Shortly thereafter, Dahl slowed and eventually ended her career as an actress, appearing only occasionally in movies and television. Dahl went on to work as a beauty and writer, and founded her own business, Arlene Dahl Enterprises, which marketed lingerie and cosmetics.
