Kristen Stewart who has recently completed her last Twilight film has finally given up her long-time habit of smoking. The 22-year-old actress asserted that she doesn’t have an addiction to nicotine and is rather more concerned about having something in her mouth all the time. “I was a bit of a faker, a circumstantial smoker, I just feel like I wasn’t addicted to nicotine. I just wanted something in my mouth,” Contactmusic quoted the actress as telling to Conan O’Brien on his late-night chat show.
