This year's Cannes Film Festival, which kicked off this morning with a photocall for Midnight in Paris, is bound to be even more star-studded than usual. Some of our favorite famous couples are bound for the event, though it remains to be seen if they'll walk the red carpets together. Brad Pitt and Kung Fu Panda 2's Angelina Jolie wowed the crowds back in 2008, while Penelope Cruz and husband Javier Bardem seem increasingly comfortable being photographed together. Sean Penn, who's debuting The Tree of Life with Brad, could bring his lady friend Scarlett Johansson, while Penelope's Pirates of the Caribbean: On Stranger Tides buddy Johnny Depp may appear with Vanessa Paradis. We have high hopes for the loved-up sightings, but tell us — which duo do you hope hits the Cannes red carpet together?
