We can imagine Kristen Stewart isn't smiling about too much these days.

But just a couple of months before K.Stew's short-lived romance with her married Snow White and the Huntsman director Rupert Sanders was exposed by a photog, the Twilight star was all smiles for a Marie Claire photo shoot, looking carefree as she hung out with her On the Road castmates.

In the shoot for the mag's September issue, Stewart donned a Blondie T-shirt, red jacket and black cut off shorts while posing solo in a pool in Cannes, France, and poolside with costars Garret Hedlund and Sam Riley.

And this may be the most will see of Stewart for now (at least until the Breaking Dawn premiere).
