Christina Aguilera is seriously looking better than EVER!

The 32-year-old singer showed off her dramatically slimmed-down physique on last night's episode of The Voice when she performed with Jacquie Lee and Matthew Schuler. Aguilera and her team sang a mashup of Janet Jackson's "Black Cat" and Michael Jackson's "Scream" and "Bad," and both Lee and Shuler will be moving to the Top 8.

Christina also appears in the new music video for A Great Big World's hit sing "Say Something," and though she wasn't on the original track, after singers Ian Axel and Chad Vaccarino re-recorded it with Aguilera and performed the new version on The Voice earlier this month, it exploded on the charts.
