The crowd was so borderline D-list that we had to ask our fellow red carpeteers (several times) who everyone was. And when the girls from Us don't know who's coming down the line, you know it's bad. On the good end, there was Rihanna, Amerie, Adam Beach, Ice-T, and Alan Cumming, who admitted to having come for the gift bag. "I re-gift, in a very Robin Hood–like way," he said. "I'm always saying things to my friends like, 'What would you like for your birthday? How about an espresso maker? Because I've got four!'" On the bad end, there were American Idol rejects we can't bring ourselves to name or care about. But a hot performance by Rihanna redeemed the night. We exited with best song ever "Umbrella" ringing in our heads. And some free shampoo. Jada Yuan
