She may be well into her pregnancy, but that didn't stop Reese Witherspoon from bringing her A game on the red carpet Monday night.

The expectant actress was stunning in a floor-length navy gown as she promoted her forthcoming flick "Mud," alongside Matthew McConaughey.

Witherspoon, who is glowing in her second trimester, was among the hordes of celebrities who turned out for the Cannes Film Festival -- and the "Sweet Home Alabama" sweetheart was rubbing elbows with the best of them. The actress and husband Jim Toth supported friend Nicole Kidman at a special dinner feting Kidman's new film, 'The Paperboy."
