Notice how the camera knows to focus on Justin. It knows what's up. (via reddit)

This photo doesn't look staged at all, but I would bet good money that Justin Timberlake was thinking "this is going to blow up tomorrow. Man, I'm so cool" right as he leaned down to photobomb this redditor and his friends. That's always the thing with Justin: he's really good, but he knows it and it shows. On the other hand, we don't have many actually good performers left, and he's one of them. He's like an 8.5 on the Beyonce scale. I'm just calling it like I see it. Although, I think he did an even better job with his concert photobomb than she did with hers
