ICYMI: Katy Perry, Sen. Warner, Zuckerberg friend each other at Facebook HQ

Pop singer Katy Perry, Sen. Mark Warner (D-Va.), and Facebook founder Mark Zuckerberg convened last week in Palo Alto, Calif., at the social networking company's headquarters.

Warner tweeted that the trio discussed "the need to support innovation in America." 

Here's the photographic evidence, again per Warner's Twitter feed. 

Perry alluded to the outing the day before it occurred, posting a photo of herself and Zuckerberg on separate magazine covers. "FACEBOOK HERE I COME!" she tweeted

She didn't appear to mention Warner in any comments. Day-of tweets included notes to friends and a photo of an animal bed shaped like the head of a cat.
