Rihanna was pretty busy at last night's Grammy show. Before taking the stage for her own performance, she played a huge role in Eminem's live take of "Love the Way You Lie." She then returned to the award show to perform her own giant single, "What's My Name," with some help from Drake. Their chemistry, both in the studio and onstage, is pretty strong. Hell, it even got Drake to relax a bit as his awkward hand movements were rarely seen throughout the performance.
