Kristen Stewart is known for not letting much slip when it comes to her relationship with Twilight costar Robert Pattinson. But at the Cannes premiere for his new movie, Cosmopolis, she came close to having a slip of another kind.
While walking the red carpet — separately from her main man, natch, but with his BFF and her On the Road costar Tom Sturridge — the actress had cameras flashing more than normal when she almost suffered a wardrobe malfunction in her stunning red Reem Acra dress. The floor-length gown featured a plunging V neckline that showed cleavage (gasp!) — something we’re not used to seeing on the typically covered-up starlet, who was in town to promote the Jack Kerouac adaptation.
