For V magazine's new "Youth Quake"–themed issue, singers Sky Ferreira, Grimes, and Charli XCX got dressed up in Givenchy by Riccardo Tisci's fall 2012 collection and posed with an adventurous white mouse, which scrambled around on Ferreira's star-encrusted shoulder. See a behind-the-scenes video from the cover shoot, which was photographed by Sebastian Faena and styled by Carine Roitfeld (yes, she's also in the video, and no, she does not touch the rodent).
