Katy Perry is seriously going all out for Witness promo!

She’s so excited and willing, in fact, that she’s actually agreed to be a live art installation at the Whitney Museum!

The singer hid under a table in a small room with her head poking through and covered with a cloche. Harper’s Bazaar‘s Derek Blasberg was there to facilitate, and went around asking unsuspecting museum goers if they would be interested in viewing an art exhibit by artist Katheryn Hudson (Katy’s real name).

The best part is when the museum goers freak out when Katy starts talking. LOLz!

Watch all the fun for yourself (below)!
