Kristen Stewart Is Red Hot At 'Cosmopolis' Premiere

Perhaps a bit of vampire Bella has rubbed off on "Twilight" starlet Kristen Stewart because the actress was all about the blood reds at the Cannes Film Festival today for the premiere of Robert Pattinson's "Cosmopolis."

The brunette stunned (literally, our jaws dropped!) in a plunging Reem Acra gown with peek-a-boo lace back. Kristen complemented the frock with sparse accessories—a simple gold bracelet and ring—scarlet lips and a messy up-do. It's probably safe to say this is the most daring style statement the 22-year-old has made to date, and we love it. (We're betting a certain well-coiffed Brit did too!)

Kristen walked the carpet with her "On the Road" co-star (and Rob BFF) Tom Sturridge. The pair, along with co-stars Kirsten Dunst and Garrett Hedlund, debuted their Jack Kerouac adaptation at the festival earlier in the week.

Though the November release of "The Twilight Saga: Breaking Dawn - Part 2" marks the final time we'll see Rob and Kristen as vampire loves, it's clear from Cannes that we haven't seen the last of these two together. Swoon.
