According to The Hollywood Reporter, Emily Blunt is set to don designer togs as the latest addition to Fox 2000's The Devil Wears Prada. Anne Hathaway and Meryl Streep already have boarded the adaptation of Lauren Weisberger's best-selling tome, which is set at a glitzy Manhattan fashion magazine.

Blunt will play Emily, the magazine's senior assistant and loyal servant to despotic editor Miranda (Streep). Hathaway will play Andrea, a Brown University grad and wannabe writer who lands the coveted but nightmarish job as Miranda's assistant. David Frankel will direct the Aline Brosh McKenna-penned screenplay.
