We're clearly fans of Demi Lovato here at Complex, so we couldn't be more pleased with her outfit selection for the 12th annual Latin GRAMMY Awards last night. She rocked a Roland Mouret gown with a neckline so deep it might have even made Jennifer Lopez jealous. Demi wasn't as pleased as we were, though. "I'm bummed that my red hair didn't stay very well," she tweeted. Luckily the gown did.
