The beehive is one of the most involved hairstyles (in our opinion). Between all the hairspray and teasing, we end up spending way too much time trying to get this retro hairdo . And when your hair isn't really long, it can be even harder to achieve. Or at least, that's what we thought until we saw Marion Cotillard's beehive hairstyle at Cannes.

The French actress managed to transform her shoulder-length bob into a massive bouffant for the premiere of her new movie "Blood Ties ." Cotillard's gravity-defying updo balanced out her pleated Dior mullet gown perfectly, but we're still perplexed.

After checking out a rear view of the star's hair, we're almost convinced that her stylist Robert Vetica pulled off the '60s look without hair extensions or a single Bumpit . Check out the photos below and tell us what you think.
