A year ago Christina Aguilera was pictured at the AMA awards having put on a significant amount of weight. One year later she’s dropped it all. The singer looked more like the Christina Aguilera we got introduced to many years ago. ‘The Voice’ USA Judge, turned up at the AMAs wearing an elegant and gleaming white maxi gown. Its hard not to describe the dress as incredibly sexy. She matched the outfit with diamond cutout earrings. In our opinion she was one of, if not the best dressed at the awards. What do you think of the outfit ?
