Blake Lively at the Grace of Monaco Cannes Premiere

Blake Lively walked the red carpet at the Cannes Film Festival premiere of Grace of Monaco on Wednesday. She looked stunning in a burgundy Gucci gown — and showed off her toned legs with a supersexy slit — while posing for photos just a few feet away from Zoe Saldana. The screening of the Nicole Kidman-starring biopic also marked the opening ceremony of the festival. Blake touched down in the South of France earlier this week to begin her duties as the L'Oréal Paris ambassador; she was named the face of the brand back in October 2013.

Before popping up at Cannes, Blake hit the red carpet with her husband, Ryan Reynolds, at the Met Gala in NYC earlier this month. The couple showed off lots of sweet PDA at the event and easily took home the award for hottest couple of the night. In addition to getting glam for the gala, Blake has been staying busy filming her latest project, Age of Adaline, in Canada.
