Christina Aguilera

Look which former "Dirrty" girl has cleaned up her act (and lost a few dress sizes)! It's none other than Christina Aguilera, who looked better than she has in years at the Season 4 premiere of "The Voice" in Hollywood on Wednesday evening. A face free of clown makeup and a sensible-yet-stylish LBD are working wonders for the former Mouseketeer ... as are those sky-high Louboutins! (3/20/2013)
