VIDEO: Kristen Stewart Visits 'Today'

It might not seem like it, but Kristen Stewart has a really tough job when it comes to promoting New Moon. Sure, she gets to fly all over the world, but she and the rest of the cast are constantly in hotel rooms or doing rounds of interviews, even if they don't feel quite up to it. K-Stew soldiered on this morning, appearing on Today to chat about her new Twilight life as "the coolest opportunity," as well as becoming Joan Jett.
