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.
We think Lovato was gorgeous in all three looks, but want to hear what you think. So vote in our poll below, and leave your thoughts in the comments!
