Wowing the Cannes crowds at the red carpet premiere of boyfriend Robert Pattinson's racy thriller Cosmopolis, Kristen Stewart came perilously close to a wardrobe malfunction in a daring, blazing-red gown with a plunging, open neckline.
The 22-year-old Twilight actress posed with On The Road co-star and pal Tom Sturridge, but kept away from her tuxedoed beau Rob.
The pair are apparently contractually obliged not to appear together at non-Twilight-related red carpet events, which could explain why Rob and Kristen stayed apart at her On The Road premiere last week.
Still, the couple were recently snapped in Cannes sneaking out of a VIP party for an intimate moment on a terrace (see the video below for more).
Kristen is no stranger to showing a bit of skin, although she'd prefer to do it on the silver screen (she goes completely naked for a threesome in On The Road).
Where's my bra?
Meet my pal, Not-Rob.
Imagine if she'd worn it back to front ... disaster!
