The Harry Potter star ditched her usual frocks for a fierce suit as she arrived at the Ed Sullivan Theatre to appear on the Late Show With David Letterman.
Emma sizzled in a her tailored two-piece, which she paired with a crisp white shirt buttoned all the way to the top.
The starlet added a feminine touch to her look with pointed patent heels while toting a boxy metallic silver clutch.
And although Emma has enjoyed showing off her longer locks recently, this time she whipped her tresses back into a messy updo.
Beauty-wise the starlet packed a punch with a slick of bright red lippy teamed with kohl-rimmed eyes, rosy cheeks and bold brows.
Emma appeared on the talk show to discuss her new film Noah, in which she stars alongside Russell Crowe, Jennifer Connelly and Ray Winstone.
But this isn't the first fabulous outfit she's worn while promoting the movie - Emma oozed glamour in a beautiful navy gown at the Berlin premiere, before stunning in a monochrome jumpsuit for the Madrid screening of her new flick.
Good work, Em!
