Lady Gaga's ARTPOP album/app campaign is in full force, and she's out and about to promote her forthcoming collaborations with Inez & Vinoodh, Marina Abramovic (who just launched a Kickstarter for her performance art institute), Jeff Koons, and Robert Wilson.

In addition to sharing the single cover for "Applause" on Twitter tonight (photographed by Inez & Vinoodh) and a video of herself getting her septum pierced last week, Gaga made appearances at Robert Wilson's benefit for The Watermill Center (on stage with art auctioneer Simon de Pury and in the audience with Marina Abramovic). Gaga, Marina, and Wilson posed on a haystack and ate a body-shaped, bloody cake before Gaga played auctioneer with de Pury and expressed her gratitude for everyone's attendance at the dinner.

Whether or not Rick Ross was there, the event seems like a solid precursor to what Gaga has in store with these artists. People are speculating that Marina and Robert are a part of her upcoming VMA performance. Check out photos and a video of them below.
