From the MoMA Garden Party last month.

Last night Kanye West played that "secret" free show, which ended up being at the gorgeous Williamsburg Savings Bank in Brooklyn (the event was hosted by Heineken). Check out some video below, along with the new long-awaited video for his song "Monster" (seriously worth watching, in all its cannibalistic, beheaded, torture porn glory). But first, let's talk about the Kanye + MK gossip, which is that Kanye West, while in New York City celebrating his 34th birthday, hooked up with Mary-Kate Olson. Oh, Kanye.

Allegedly the two were at Submercer in SoHo on Wednesday when this all went down. There doesn't seem to be any photographic evidence, but you can see the world's most disturbing Photoshop portraying this story right here.

As for last night's show, many of the attendees seemed to be VIPs, with Diddy, Estelle and Jay-Z all on the list... though rumor has it Jay-Z never showed (at least he was at MoMA's Garden Party). Check out "Runaway" below, and you can see more photos and video from the show here.
