Christina Aguilera is a fighter.
The Voice coach got choked up during the rehearsals for the 2013 People's Choice Awards, but soldiered on through an emotional performance Wednesday.
Opting for a simple white blazer and black slacks instead of her usually more, um, eclectic wardrobe, Xtina performed "Blank Page" live for the first time. Watch:
The subject matter is heavy for Christina, 32.
"She was very emotional," an insider said. "The song is about making mistakes and realizing you can't go back but you can start over with a blank slate."
