The singer arrived on the red carpet in Universal City, Calif., working a beaded and feathered creation (left, reminiscent of her first X Factor frock), plus sky-high heels and a super-tall ponytail. Halfway through the show, she changed into a peekaboo black-and-white creation with a bright yellow waistline and chunky necklace (center).
By the end of the show, Lovato slipped into a third outfit, a little black dress with exposed midriff, covered with a studded leather jacket (right). But what really stood out was her hair: gone were her pink ends, and in their place, blue! (Now that’s a quick change.) It turns out the starlet went to Nine Zero One salon earlier in the weekend, getting ombré color that fades from green to blue.
