Darren Criss had a big night at the Emmys, and he had his best girl by his side for the whole thing. On Monday night, the American Crime Story actor attended the award show with his fiancée, Mia Swier, and their sweet appearance practically gave us a toothache. In addition to showing off their love on the red carpet, Darren gave an adorable shout-out to Mia during his acceptance speech for lead actor in a limited series or movie. "You roll the windows down and you pump the music up in my life," he said. See more photos from their night ahead.
