Kristen Stewart is even more “grungy” in real life than her public persona.

The Twilight actress - famed for her jeans, T-shirt and trainers style - says she is an extremely casual dresser and rarely puts on glamorous clothes for the cameras. During a recent photo shoot she joked, “People think I’m grungy now - and I know that I’m being photographed!”

Kristen did admit, however, she enjoys picking out designer clothes when she does succumb to appearing in fashion shoots. She told Elle, “I’m fine when I’m chilling with my hair and makeup crew - I like choosing what I am going to wear.”

The actress - who is in a relationship with her Twilight co-star Robert Pattinson - also shuns the fame the film has brought her saying, “I can’t be by myself, and I like being by myself.”

Kristen recently defended her seemingly upset appearance in public -particularly on the red carpet at film premieres - claiming it is a reaction to the way people treat her: “People say that I’m miserable all the time. It’s not that I’m miserable, it’s just that somebody’s yelling at me. I literally, sometimes, have to keep myself from crying. It’s a physical reaction to the energy that’s thrown at you.”
