See Christina Aguilera's transformation from AMAs 2012 to AMAs 2013
Not only has the pint-sized singer slimmed down, but she's rocking a much more elegant look. We also love, love, love her 2013 AMAs performance of "Say Something" with A Great Big World. It too is in sharp contrast to her 2012 AMAs performance of a "Lotus" medley and "Feel This Moment" with Pitbull.
Not that those performances were bad, per se, but her "Say Something" was a highlight of the night for us.
It's terrific how slim and trim she looks while not looking unhealthy. Whatever you're doing, XTina, keep it up.
