Kristen Stewart was smiley and happy as she stepped out in a colorful Peter Pilotto dress to chat with Jay Leno for The Tonight Show in LA on Monday evening. Kristen spoke to Jay about the final Twilight movies, Breaking Dawn Part 1 and Part 2, saying, "Popped one out — pretty concerned with that. Me and Edward are doing quite well; people keep trying to kill my baby. But I'm now superspectacular, so I can take care of that, being a vampire." Kristen also touched on Breaking Dawn Part 2's twist ending: "Every time I see it or even think about it, I get giddy. It freaks me out. . . . It's easy to skim over. But you can find the root of our little twist [in the book]." Kristen switched gears from her blockbuster franchise to promote her indie project On the Road over the weekend. Kristen premiered On the Road at the AFI Festival in LA on Saturday, and she was joined by boyfriend Robert Pattinson at that afterparty. While Kristen was chatting with Jay, Rob was elsewhere in town making his own appearance on Jimmy Kimmel's show.
