Celebs in Sombreros

It’s Cinco de Mayo. Though many believe it marks Mexico’s Independence Day, the holiday actually commemorates the Mexican army’s victory over the French forces of Napoleon III on May 5, 1862, at the Battle of Puebla. But let’s face it — most people use Cinco de Mayo as an excuse to party. So break out the tequila, slap on a sombrero, and let the fiestas begin!
