Conan O'Brien is nerding out at Comic-Con, and by nerding out, we mean that he's definitely hanging out with a bunch of A-listers. Last night, the late night host with the most had the pleasure of interviewing Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth (aka the cast of "The Hunger Games: Mockingjay -- Part 2") and Josh accidentally revealed that they're planning another movie....But wait, it gets better. Jennifer Lawrence sang Cher's "Believe." You're welcome, world.
