Stars are putting it in neutral at Cannes! Vanessa Hudgens (left) chose a sand-hued Fendi gown for The Art of Elysium 3rd Annual Paradis event, while Rachel McAdams (center) turned up the sparkle at the premiere of Sleeping Beauty in a khaki embellished Monique Lhuillier bustier top and matching wide-leg pants. And Rosario Dawson (right) hit the red carpet at Calvin Klein's Cannes bash in a putty-colored frock by the designer.
