Rihanna twerked behind Drake during a surprise performance of their hit single 'Work' at her 'ANTi' world tour stop in Miami last night.
Miami’s American Airlines Arena roared like mad when he and Rihanna briefly grinded on each other during the scorching hot performance. These two have chemistry for days, and of course it doesn't hurt when keeping the song at number one on the Billboard Hot 100. Can they hold on to the top spot for a fifth consecutive week? Get that promo.
