Christina Aguilera made a surprise appearance at an event promoting the new season of The Voice, showing off her slimmed down figure in a chic black mini-dress. It's a far cry from the curvier Christina we saw at November's American Music Awards.
"I feel like superwoman," said Aguilera. "I actually can't wait to get some inside info on what the new season is like with the new dynamic."
Christina and Cee Lo Green have left their judges chairs. Shakira and Usher are stepping in. Season 4 of The Voice kicks off Monday.
