Christina Aguilera's New Svelte Look At 'The Voice' Season 4 Screening (VIDEO, PHOTO)

Christina Aguilera is no stranger to controversy over her changing style but the singer looked better than ever on the red carpet at a screening of NBC's 'The Voice' Season 4 on March 20.

The "Your Body" singer ditched her usual dramatic makeup and opted for a more natural beauty look. Instead of bright red lips she wore a peach gloss and she held back on the mascara and eyeliner.

Aguilera also showed off her new, svelte body in a short cocktail dress with an on-trend studded belt.

And she wouldn't be Christina Aguilera, diva extraordinaire without the sky-high Christian Louboutin stilettos.

Wow, did she look different back in the day...
