As celebrity goes, you can't get much bigger than Beyoncé or the Obamas. So it stands to reason that when the Obamas attend a Beyoncé concert, minds are blown.

Over at TMZ, there's an image of Yesenia Herrera of Instagram subtly restraining her duck face with Sasha, Malia and Michelle Obama singing along to, maybe, "Single Ladies" behind her. No, more like "Flawless," if I'm going to go by their faces. Either way, this image shows that security wasn't really on the job. Come on Secret Service, I know you guys probably have a lot on your plate with the world melting and all, but it's the first family. You must protect them from the selfie invasion.
