Twilight star Kristen Stewart was recently caught screaming at a photographer that he didn't deserve to breathe the same air she does.

When the photographer reportedly questioned Stewart about her relationship with her ex boyfriend Robert Pattinson, she called him a f*** face.

At one point, Stewart got so heated up when she was quizzed as to why she asked him to go away that she literally screamed at the paparazzo.

"Because you're a piece of s***. You don't deserve to breathe the same air I do," she screams.

Pattinson and Kristen Stewart split recently for the second time after she rekindled her affair with Snow White and the Huntsman director Rupert Sanders. All hell broke loose between the erstwhile golden couple last year when Stewart confessed to having an affair with Sanders behind Pattinson's back.

She also issued an apology later for cheating on Pattinson. "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardised the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry," Stewart stated.

Meanwhile, Pattinson has been spotted partying with Fast and Furious actress Michelle Rodriguez at the Chateau Marmont in Hollywood. That's not all, he was also reported to be dating Elvis Presley's granddaughter, Riley Keough. Pattinson was spotted with The Runaways starlet, who was previously engaged to Alex Pettyfer at his Los Angeles home last month.

However, a rep for the actress confirmed that she was not the mystery girl photographed riding in Pattinson's truck on 29 June.

"Riley isn't dating Rob. And I can confirm that Riley was not photographed at all this weekend," a rep for the 24-year-old actress told Just Jared.

Pattinson was also linked with his co-star in the Dior ad, model Camille Rowe. His sizzling chemistry in the ad with the French blonde beauty led to several speculations. Rowe has also appeared in campaigns for H&M, Gap, Rag & Bone and Coach.
