For Friday's premiere of "Cosmopolis," Cannes 2012 mainstay Kristen Stewart ditched the Balenciaga pants and went bold, bold, bold in a sexy red Reem Acra gown -- that almost revealed more than she probably wanted.
Though she's (now pretty much confirmed to be) dating "Cosmopolis" star Robert Pattinson, Stewart walked the red carpet in the south of France with Tom Sturridge, her "On the Road" costar, and radiated sexy glam in a scarlet dress dotted with lacy cutouts.
But Stewart's plunging neckline was definitely risky, resulting in a view of some pretty daring cleavage. Luckily, it seems some double-sided tape prevented any major accidents.
Cannes has definitely been bringing out the wardrobe malfunction-risking dresses -- from totally sheer bottoms to fellow plunge-rs. Check out Kristen's dress below, and see other sideboob-baring celebs in our slideshow.
