All eyes were on Robert Pattinson as he stepped out onto the red carpet at tonight's Cannes Film Festival premiere of his David Cronenberg-directed thriller, Cosmopolis. Rob kicked off his day at a casual photocall for the film, but for tonight's formal affair he suited up in a tuxedo. He was joined on the carpet by costars Sarah Gadon and Juliette Binoche. However, he was just a few feet away from his number one lady, Kristen Stewart, who posed for photos with Tom Sturridge. Rob showed his support for Kristen and Tom's feature, On the Road, at a screening earlier in the week and Kristen and Tom seemed happy to do the same for Rob. Early reviews of Cosmopolis have been tough on the storyline, but Rob's fans will be able to make their own judgements when the film hits theaters later this year.
