Kristen Stewart and On the Road Co-Stars in US Marie Claire

Kristen Stewart joins her On the Road costars Garrett Hedlund and Sam Riley for a photo spread inside US Marie Claire's September issue. Miley Cyrus posed for the cover, while Kristen and the boys teamed up for a few key promotional shots. The images were taken in May during the Cannes Film Festival, where Kristen was promoting her Jack Kerouac adaption and boyfriend Robert Pattinson was celebrating the Cosmopolis world premiere, which she also attended. Since then, things have taken a dramatic turn for the couple. Last month photos of Kristen cheating with Rupert Sanders shocked fans, and she's remained in hiding ever since. As for Robert, he temporarily moved out of their shared residence and relocated to Reese Witherspoon's Ojai estate; he'll make his first public appearances since news of the scandal when he visits The Daily Show With Jon Stewart on Monday and Good Morning America on Wednesday.
