One runway trend that's making its way to Hollywood is bold, bright lips. Last night, the celebrities showed off a garden variety of lipstick shades, including pink, purple, and red. Kat Dennings attended the premiere of Iron Man 3 with hot-pink lips paired with icy silver eye shadow. At the Tribeca Film Festival Chanel Artists Dinner, Taraji P. Henson complemented her blue ensemble with an electric purple lipstick, and Olivia Palermo rocked a blazing red hue at a Rochas event. When it comes to lipstick this season, live by the motto: the brighter the better.
