At Fair Game cocktail party hosted by Giorgio Armani in Cannes, Blunt wore Streicher's favorite lip hue.

The newlywed supported husband John Krasinski at the Emmy Awards. "We wanted a style that was very different from any that Emily had worn before," said Reeves.

"Emily wanted smoky eyes paired with soft pink lips that echoed her Lorraine Schwartz ruby earrings," said the star's makeup artist Jenn Streicher of her Golden Globes look. After creating a smooth canvas, she defined Blunt's eyes with Hourglass's Kohl Eye Pencil in Espresso and smudged the line with a shadow brush.
