Pop star Katy Perry swung through Facebook's headquarters for a visit. What did she do there? Pose with employees, eat at the cafeteria, and not much else as far as we can tell. But it looked fun for the employees!

We picked through a big batch of photos from her visit that were posted on Facebook.

One thing that stands out: Perry's decision to wear big heels made her tower above Facebook's employees. Or, alternatively, the people at Facebook are just short. Photos of Perry and Facebook founder Mark Zuckerberg below.
