Christina Aguilera has come in all sizes, from extra small to large. While we think she looks amazing with some curves, she's taken quite a bit of heat over the years for her ups and downs, but wait until you see this! Xtina showed up to a screening of The Voice's Season 4 premiere Wednesday night looking beautiful in every single way! Sporting a sweet but sophisticated LBD, Christina showed off a significantly slimmer figure. Even her hair and make-up were toned down.
