Did your heart melt a little bit when you saw Ryan Gosling and Brad Pitt take the stage together last night? Were you standing so close to the screen that your eyes hurt from the perfection that was The Big Short co-stars' onstage banter? Selena Gomez is right there with you.Whether or not their bit was funny isn't really what's important here. What's important (very important) is that the moment is now etched in our memory for forever. Pitt looked more youthful and radiant than ever, and Gosling proved that white suits can be the most dapper. The world swooned.Selena was no exception.
