The 2011 Cannes Film Festival got off to quite the glamourous start in the South of France on Wednesday, with some of Hollywood's hottest stars stepping it up big time on the red carpet. We still have almost a week of gorgeous gowns to come, but at this rate, the festival might trump the Met Gala as the most fashionable event of the season.

So let's take a look at the best dressed stars so far. First up, is Salma Hayek in a gray strapless beaded gown by Gucci Premiere, the brand's couture label. Sure, it's not the most original design, but at 44 years old, Hayek looks more stunning than ever.

More than a few jaws hit the floor when Diane Kruger showed up at the premiere of Sleeping Beauty in a figure-hugging Calvin Klein Collection gown that looked like liquid gold on her. What's even more impressive is that the 34-year-old doesn't regularly use a professional stylist.

While her choice of pants for the red carpet is questionable, you can't argue that Rachel McAdams looked super chic in her Monique Lhuillier wide-leg trousers and sparkly bustier. Bonus points for the 32-year-old's choice of lipstick.
 
Uma Thurman, 41, turned heads in a white strapless Versace gown with a low-cut back, thigh-high slit and feather accents. She accessorized with striking emerald Chopard earrings and matching bracelet.
