Stressed Out? Moody Kristen Stewart Spotted Puffing On Cigarette On Set Of Camp X Ray

It’s not been the easiest few months for Kristen Stewart following her split with boyfriend Robert Pattinson and it seems the strain is getting to the actress as she was spotted looking stressed out on the set of new movie Camp X Ray as she puffed away on a cigarette.

The 23-year-old began shooting her first movie since Twilight: Breaking Dawn Part 2 was released in Los Angeles last week, taking on the role of a US Marine who is stationed at Guantanamo Bay who strikes up an unlikely friendship with an inmate.

Kristen rocked her usual relaxed style on set, wearing jogging bottoms a vest, hoodie and sunglasses as she snuck off for a cigarette break and looked thoughtful as she puffed away.

The indie drama will see Kristen take on a far gritter role than we’ve previously seen her in with the actress most famous for her turn as high school student turned vampire, Bella Swan in Twilight, with the brunette sported a battered, swollen lip during her break – so no wonder she needed a bit of relief!

Last week the actress was seen in full Marine’s uniform as she shots scenes off the coast of Los Angeles along with co-star Lane Harrison. The tough guy role more than suits Kristen’s tom-boy persona, who is known to not be a fan of the girlie roles.

Getting back to work will no doubt come as a relief to the actress following months of speculation about her private life. The star and then boyfriend Robert Pattinson spent most of 2013 apart while he filmed new movie The Rover in Australia before he returned at the end of March. After only a month together in LA the couple split at the beginning of May, according to insiders after four years together.

Since then the actress has faced a barrage of rumours about why their romance went wrong, with most citing her fling with married director Rupert Sanders as the final nail in the coffin, claiming Rob was unable to move on from it.

Last week marked a year since the actress’ affair was exposed, with a slew of shots of the couple kissing published by US tabloid Us Weekly.
