Mariah Carey's big comeback hit a sour note at Tuesday night's American Music Awards. The pop diva went into the ceremony with a leading four nominations, but went home with just one trophy: favorite female soul-R&B artist. Still, Carey wasn't the night's biggest loser. That honor goes to the show itself, which was hampered by more absentee honorees than a Razzies ceremony. Among the MIA winners: Green Day, the Black Eyed Peas, Eminem, Kelly Clarkson and 50 Cent. Heck, they couldn't even get Michelle Williams from Destiny's Child to show up. Not. Good. At. All.
