17 People We Really Wish Had Shown Up at the Grammys

The singer had to cancel her planned Grammys performance just an hour before hitting the stage. Rihanna was reportedly dealing with a case of bronchitis and an on-site doctor at the Staples Center recommended that she not perform because she could permanently damage her vocal cords. She tweeted out a message to fans, saying, "So sorry I couldn't be there. . . Thanks Grammys and CBS for your support tonight." While we appreciate the sweet apology, Rihanna's presence really would have made the show that much more awesome.
