The duo were backstage at the Topshop Unique show  on Sunday with fellow model Rosie Tapner when cameras captured Dunn following the meme's custom of breaking into a spontaneous dance to the Baauer song "Harlem Shake." Delevingne and Tapner don't seem particularly amused to be in the middle of a dance party until they suddenly join in on the fun.
Iterations of the Harlem Shake video have come from the campuses of West Point  and the University of Texas , and to the offices of BuzzFeed  and Anderson Cooper Live . Given how much the fashion industry likes its memes , we're a little surprised it took this long for someone to make a version, but we're excited to see the ones that might follow it. Your move, Alber.
