At Cannes, Kristen Stewart goes glam and kisses Robert Pattinson

kristen-stewart-cannes-2012-3-gi.jpg Kristen Stewart is a knockout, no question about it. But the "Twilight: Breaking Dawn - Part 2" star is cranking up the glam at Cannes where she's promoting her other upcoming movie -- the one that isn't "Snow White and the Huntsman" -- "On The Road." She's also making headlines for a snapshot of her kissing boyfriend (and "Twilight" co-star) Robert Pattinson.

On Wednesday (May 23), Stewart rocked the red carpet in a pair of slim patterned Balenciaga pants and stilettos that were a major departure from her usual denim. Stewart has been the face of the label since January and the yellow patterned pants are officially a hit, if inspiring a heated online debate about their actravtiveness counts as a hit.

Then, on Thursday, she joined her "On the Road" co-stars at the screening in more Balenciaga -- this time an embroidered gown with a high-slit to rival Angelina Jolie's Oscar look.

She was also spotted (though we're not sure if she was wearing Balenciaga or not) snogging with Pattinson at an "On the Road" after party.
