Best and Worst: Rihanna
We love Calvin Harris and Rihanna's track, "We Found Love," but the pop superstar continues to prove she can't really duplicate her voice outside the studio. The dancing was fantastic, but the more Rihanna sings live the less we want to hear her. Although we'll give her props for bringing a club atmosphere to Staples Center. It looked like Limelight in the mid-90's in there all over again.
