According to Us Weekly, Leighton Meester and Adam Brody are now dating. ... which is weird, because I thought they have been together for years. I made that awful assumption based on the awful shows they both have starred in. I guess I just automatically assume the stars of tween shows (like Ian Somerhalder and Nina Dobrev) just automatically date each other. They're all hot and work together every day so they have to end up banging, right? Right. Romantic comedies taught me everything.
