His mother, Bonny L., is a retired high school teacher, and the Executive Director of Minot's Downtown Business & Profession Association, and his father, Larry Duhamel, is an advertisement salesman. Josh has three younger sisters: Ashlee, McKenzee and Kassidy. His ancestry is German, and smaller amounts of Norwegian, French-Canadian, English, Irish, and Austrian (his last name is very common among Francophones in the world). Before his acting career, the football player studied biology and earned his Bachelor's degree at Minot State University with the intention of pursuing dentistry.
When Josh was 26 years old, he worked in the construction business, and it was by chance that he got into the entertainment business. Modeling eventually gave way to acting as Josh was asked to audition for the title character in The Picture of Dorian Gray (2005), from the novel by Oscar Wilde.

In addition, Duhamel was seen in the star-studded, ensemble comedy "Movie 43" alongside Emma Stone, Hugh Jackman, Halle Berry, Kate Winslet, Richard Gere among many others. Co-directed by Peter Farrelly and Patrik Forsberg, the film features various intertwining, raunchy tales.
